+INTRODUCTION TO ARCNET
+----------------------
+
+ARCnet is a network type which works in a way similar to popular "ethernet"
+networks but which is also different in some very important ways.
+
+First of all, you can get ARCnet cards in two speeds: 2.5Mbps (slower than
+ethernet) and 100Mbps (faster than ethernet). The two hardware types, as
+far as I'm aware, are not compatible and so you cannot wire a 100Mbps card
+to a 2.5Mbps card, and so on. From what I hear, my driver does work with
+100Mbps cards, but I haven't been able to verify this myself, since I only
+have the 2.5Mbps variety.
+
+You also cannot connect an ARCnet card to any kind of ethernet card and
+expect it to work.
+
+There are two "types" of ARCnet - STAR topology and BUS topology. This
+refers to how the cards are meant to be wired together. According to all
+available documentation, you can only connect STAR cards to STAR cards and
+BUS cards to BUS cards. That makes sense, right? Well, it's not quite
+true; see below under "Cabling."
+
+Once you get past these little stumbling blocks, ARCnet is actually quite a
+well-designed standard. It uses something called "modified token passing"
+which makes it completely incompatible with so-called "Token Ring" cards,
+but which makes transfers much more reliable than with ethernet. In fact,
+ARCnet will guarantee that a packet arrives safely at the destination, and
+even if it can't possibly be delivered properly (ie. because of a cable
+break) it will at least tell the sender about it.
+
+In addition, all known ARCnet cards have an (almost) identical programming
+interface. This means that with one "arcnet" driver you can support any
+card; whereas, with ethernet, each manufacturer uses what is sometimes a
+completely different programming interface, leading to a lot of different,
+sometimes very similar, ethernet drivers. Of course, always using the same
+programming interface also means that when high-performance hardware
+facilities like PCI busmastering DMA appear, it's hard to take advantage of
+them.
+
+One thing that makes ARCnet cards difficult to program for, however, is the
+limit on their packet sizes; standard ARCnet can only send packets that are
+up to 508 bytes in length. This is smaller than the internet "bare minimum"
+of 576 bytes, let alone the ethernet MTU of 1500. To compensate, an extra
+level of encapsulation is defined by RFC1201 called "packet splitting" which
+allows "virtual packets" to grow as large as 64K each, although they are
+generally kept down to the ethernet-style 1500 bytes.
+
+
+CABLING ARCNET NETWORKS
+-----------------------
+ - Information in this section is from several contributors, including:
+ Stephen A. Wood <saw@hallc1.cebaf.gov>
+ John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
+ Joachim Koenig <jojo@repas.de>
+ Vojtech Pavlik <vpav4328@Diana.troja.mff.cuni.cz>
+
+ - I, Avery Pennarun, tried to arrange it into something that makes sense
+ when all put together. All mistakes, then, are most likely my fault.
+ Bug me about them.
+
+Ideally, according to documentation, ARCnet networks should be connected
+with 93 Ohm cables with 93 Ohm resistors as terminators. I use TV cable and
+no resistors to connect two STAR cards. Blah. Your mileage may vary.
+
+Here's some more specific information about cables, sent in by Joachim
+Koenig (slight touchups by me):
+
+ The following cables are valid for ARCnet:
+ RG-62 93 Ohm up to 610 m
+ RG-59/U 75 Ohm up to 457 m
+ RG-11/U 75 Ohm up to 533 m
+ IBM Typ 1 150 Ohm up to 200 m
+ IBM Typ 3 100 Ohm up to 100 m
+
+So you can see that while 93 Ohms is ideal, you can still go half a
+kilometer with 75 Ohm TV cable.
+
+The above applies to all known ARCnet cards. Specific to STAR cards,
+though, Stephen A. Wood has some information:
+
+ When I bought my two cards at a garage sale, they came with little
+ box with four BNC connectors on the outside. The shields of the
+ four connectors are all grounded together, and the center conductors
+ were connected by the following resistor network.
+
+ |
+ |
+ R
+ |
+ ---R-+-R---
+ |
+ R
+ |
+ |
+
+ Where R is 47 Ohms. A little math shows that if you terminate three
+ of the outputs with 90 ohms (A cable or a terminator), the remaining
+ input sees 90 Ohms. Therefore this box is impedance matched to 90
+ Ohm cable. So this box can be used to connect 2 to 4 nodes
+ together.
+
+If you really use your imagination, you can see how the above diagram kind
+of looks like a "star." John Paul Morrison makes a few notes about the
+above:
+
+ The "little box with four BNC connectors on the outside" is an
+ Arcnet passive hub. They're worth about $5 (just so you don't get
+ ripped off).
+
+ I don't have specs at my fingertips. Basically, don't use too many
+ passive hubs (or none at all, apparently passive hubs are A Bad
+ Thing. On the other hand, they're a really cheap way to do things.)
+
+ Arcnet active hubs are available; they are analogous to Ethernet
+ twisted pair hubs. You can plug either a single station or a passive
+ hub into each port on the active hub. If you plug in a passive hub,
+ that lets you connect three more stations.
+
+According to Vojtech Pavlik, there shouldn't be more than one passive hub
+between two "active ends", an active end being an active hub or an ARCnet
+card.
+
+As for BUS cards, they're even easier (for more than two cards, anyway; you
+can't get much simpler than direct-connecting two STAR cards with a TV
+cable). They work just like Thinnet ethernet; it looks like this:
+
+ R------+------+------+------R
+ | | |
+ NODE NODE NODE
+
+Where R is the terminator as usual, and '+' represents a T connector.
+
+Okay, then, what if you have a combination of BUS cards and STAR cards? You
+probably can't do ANY combination you want, but Vojtech Pavlik explains what
+works for him (WARNING: I, Avery, haven't tried anything this weird myself):
+
+ All that I need is to terminate each end with a STAR card. I think I
+ can even connect the cards like this:
+
+ STAR------+-----+-----STAR
+ BUS BUS
+
+ Where "-" stands for coax, "+" for T connector, "STAR" for star-type
+ arcnet card and BUS for bus-type arcnet cards. I think there will be
+ no terminators necessary.
+
+He also explains (I paraphrase slightly here):
+
+ R-+----------STAR
+ BUS
+
+ In this case, I have to terminate the end with the bus card
+ using a terminator. ("R" - terminator, "+" - T connector "-" - coax,
+ everything other is probably clear)
+
+ [...]
+
+ And _MAYBE_ you can do even more complicated and insane combinations
+ when just thinking of the STAR card as a BUS one with an inside
+ installed terminator. (STAR cards are NOT bus ones with terminator,
+ but I believe that they electrically act like them).
+
+And finally, he gives a shortcut for BUS users that are low on supplies:
+
+ When you have really short cables (about four meters in total) and have lack
+ of terminators or T's you can leave one of the terminators out .... or put
+ it in the middle like this:
+
+ BUS-----T-----BUS
+ R
+
+ It's ugly, but it works.
+
+I don't pretend to understand what's happening there, but then again, I
+don't have BUS cards either.
+
+
+
+SETTING THE JUMPERS
+-------------------
+
+All ARCnet cards should have a total of four or five different settings:
+
+ - the I/O address: this is the "port" your ARCnet card is on. Probed
+ values, as of v0.14, are only from 0x200 through 0x3F0. (If your card
+ has additional ones, which is possible, please tell me.) This should not
+ be the same as any other device on your system. According to a doc I
+ got from Novell, MS Windows prefers values of 0x300 or more, eating
+ netconnections on my system otherwise.
+ - Avery's favourite: 0x300.
+
+ - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
+ on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15. Make
+ sure this is different from any other card on your system. Note that
+ IRQ2 is the same as IRQ9, as far as Linux is concerned.
+ - Avery's favourite: IRQ2.
+
+ - the memory address: Unlike most cards, ARCnets use "shared memory" for
+ copying buffers around. Make SURE it doesn't conflict with any other
+ used memory in your system!
+ A0000 - VGA graphics memory (ok if you don't have VGA)
+ B0000 - Monochrome text mode
+ C0000 \ One of these is your VGA BIOS - usually C0000.
+ E0000 /
+ F0000 - System BIOS
+
+ Anything less than 0xA0000 is, well, a BAD idea since it isn't above
+ 640k.
+ - Avery's favourite: 0xD0000
+
+ - the station address: Every ARCnet card has its own "unique" network
+ address from 0 to 255. Unlike ethernet, you can set this address
+ yourself with a jumper. Since it's only 8 bits, you can only have 254
+ ARCnet cards on a network. DON'T use 0 or 255, since these are
+ reserved. (although neat stuff will probably happen if you DO use them).
+ By the way, if you haven't already guessed, don't set this the same as
+ any other ARCnet on your network!
+ - Avery's favourite: 3 and 4. Not that it matters.
+
+ - There may be ETS1 and ETS2 settings. These may or may not make a
+ difference, but are used to change the delays used when powering up
+ a computer on the network. This is only necessary when wiring VERY
+ long range ARCnet networks, on the order of 4km or so; in any case,
+ the only real requirement here is that all cards on the network with
+ ETS1 and ETS2 jumpers have them in the same position.
+
+
+Here's the all the jumper information I could obtain for individual card
+types. Unfortunately, there is a lot of duplicated information here.
+Someday, I may get around to actually organizing it. Until then... too much
+is better than too little, I say :)
+
+The model # is listed right above specifics for that card, so you should be
+able to use your text viewer's "search" function to find the entry you want.
+
+If your model isn't listed, and has different settings, PLEASE PLEASE tell
+me. I had to figure mine out without the manual, and it WASN'T FUN!
+
+Even if your ARCnet model isn't listed, but has the same jumpers as another
+model that is, please e-mail me to say so.

+Setting one of the switches to Off/Open means "1", On/Closed means "0".
+
+
+Setting the Node ID
+-------------------
+
+The eight switches in group S2 are used to set the node ID.
+Each node attached to the network must have an unique node ID which
+must be diffrent from 0.
+Switch 1 serves as the least significant bit (LSB).
+
+The node ID is the sum of the values of all switches set to "1"
+These values are:
+ Switch | Value

+
+
+Setting the I/O Base Address
+----------------------------
+
+The first three switches in switch group S1 are used to select one
+of eight possible I/O Base addresses using the followig table
+
+
+ Switch | Hex I/O
+ 1 2 3 | Address
+ -------|--------
+ 0 0 0 | 260
+ 0 0 1 | 290

+ 1 0 0 | 300
+ 1 0 1 | 350
+ 1 1 0 | 380
+ 1 1 1 | 3E0
+
+
+Setting the Base Memory (RAM) buffer Address
+--------------------------------------------
+
+The memory buffer requires 2K of a 16K block of RAM. The base of this
+16K block can be located in any of eight positions.
+Switches 4-6 of switch group S1 select the Base of the 16K block.
+Within that 16K address space, the buffer may be assigned any one of four
+positions, determined by the offset, switches 7 and 8 of group S1.

+
+*) To enable the 8K Boot PROM install the jumper ROM.
+ The default is jumper ROM not installed.
+
+
+Setting the Timeouts and Interrupt
+----------------------------------
+
+The jumpers labeled EXT1 and EXT2 are used to determine the timeout
+parameters. These two jumpers are normally left open.
+Refer to the COM9026 Data Sheet for alternate configurations.
+
+To select a hardware interrupt level set one (only one!) of the jumpers
+IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufactor's default is IRQ2.
+
+
+Configuring the PC130E for Star or Bus Topology
+-----------------------------------------------
+
+The single jumper labeled STAR is used to configure the PC130E board for
+star or bus topology.
+When the jumper is installed, the board may be used in a star network, when
+it is removed, the board can be used in a bus topology.

+=====================================================================
+
+Note: There is another Version of the PC500 called Short Version, which
+ is different in hard- and software! The most important differences
+ are:
+ - The long board has no Shared memory
+ - On the long board the selection of the interrupt is done by binary
+ coded switch, on the short board directly by jumper.

+
+
+Setting the Node ID
+-------------------
+
+The eight switches in group SW3 are used to set the node ID. Each node
+attached to the network must have an unique node ID which must be
+diffrent from 0.
+Switch 1 serves as the least significant bit (LSB).
+
+The node ID is the sum of the values of all switches set to "1"
+These values are:
+
+ Switch | Value
+ -------|-------
+ 1 | 1
+ 2 | 2
+ 3 | 4
+ 4 | 8

+
+Setting the I/O Base Address
+----------------------------
+
+The first six switches in switch group SW1 are used to select one
+of 32 possible I/O Base addresses using the followig table
+
+ Switch | Hex I/O
+ 6 5 4 3 2 1 | Address
+ -------------|--------

+
+
+Setting the Interrupt
+---------------------
+
+Switches seven through ten of switch group SW1 are used to select the
+interrupt level. The interrupt level is binary coded, so selections
+from 0 to 15 would be possible, but only the following eight values will
+be supported: 3, 4, 5, 7, 9, 10, 11, 12.
+
+ Switch | IRQ
+ 10 9 8 7 |
+ ---------|--------
+ 0 0 1 1 | 3
+ 0 1 0 0 | 4
+ 0 1 0 1 | 5
+ 0 1 1 1 | 7
+ 1 0 0 1 | 9 (=2) (default)
+ 1 0 1 0 | 10
+ 1 0 1 1 | 11
+ 1 1 0 0 | 12
+
+
+Setting the Timeouts
+--------------------
+
+The two jumpers JP2 (1-4) are used to determine the timeout parameters.
+These two jumpers are normally left open.
+Refer to the COM9026 Data Sheet for alternate configurations.
+
+
+Configuring the PC500 for Star or Bus Topology
+----------------------------------------------
+
+The single jumper labeled JP6 is used to configure the PC500 board for
+star or bus topology.
+When the jumper is installed, the board may be used in a star network, when
+it is removed, the board can be used in a bus topology.
+
+
+Diagnostic LEDs
+---------------
+
+Two diagnostic LEDs are visible on the rear bracket of the board.
+The green LED monitors the network activity: the red one shows the
+board activity:
+
+ Green | Status Red | Status
+ -------|------------------- ---------|-------------------
+ on | normal activity flash/on | data transfer
+ blink | reconfiguration off | no data transfer;
+ off | defectiv board or | incorect memory or

+PDI507 (16-bit card)
+--------------------
+ - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by
+ Avery)
+ - Send questions/suggestions/etc about this text to Mark.
+
+Jumpers:
+
+ There is a jumper array at the bottom of the card, near the edge
+ connector. This array is labelled J1. They control the IRQs and
+ something else. Put only one jumper on the IRQ pins.
+
+ IRQ2 - Use IRQ 2 (same as IRQ 9 as far as software is concerned)
+ IRQ3 - Use IRQ 3 (used by COM2 or COM4 serial port if either exists)
+ IRQ4 - Use IRQ 4 (used by COM1 or COM3 serial port if either exists)
+ IRQ5 - Use IRQ 5 (used by LPT2 parallel port if one exists)
+ IRQ6 - Use IRQ 6 (used by Floppy Disk Controller if one exists)
+ IRQ7 - Use IRQ 7 (used by LPT1 parallel port if one exists)
+
+[Avery's note: This "unknown" set of two jumpers appears to be on all
+ARCnet cards by SMC as well. Putting jumpers on them seems to affect the
+status register, but only for the two "reserved" bits, ETS1 and ETS2. Any
+further information is welcome.]
+
+ ET1 - What is this? (Not tested, no jumper put on it)
+ ET2 - What is this? (Not tested, no jumper put on it)
+
+ There is a J2 jumper on two pins. A jumper should be put on them,
+ since it was already there when I got the card. I don't know what
+ this jumper is for though.
+
+ There is a two-jumper array for J3. I don't know what it is for,
+ but there were already two jumpers on it when I got the card. It's
+ a six pin grid in a two-by-three fashion. The jumpers were
+ configured as follows:
+
+ .-------.
+ o | o o |
+ :-------: ------> Accessible end of card with connectors
+ o | o o | in this direction ------->
+ `-------'
+
+ There is also a J4 jumper on two pins. A jumper should be put on
+ them, since it was already there when I got the card. I don't know
+ what this jumper is for though.
+
+
+DIP Switches:
+
+ The dipswitches accessible on the accessible end of the card while
+ it is installed, is used to set the arcnet address. There are 8
+ switches. Use an address from 1 to 254.
+
+ Switch No.
+ 12345678 Arcnet address
+ -----------------------------------------
+ 00000000 FF (Don't use this!)
+ 00000001 FE
+ 00000010 FD
+ ....
+ 11111101 2
+ 11111110 1
+ 11111111 0 (Don't use this!)
+
+ There is another dipswitch array of 8 switches at the top of the
+ card. There are five labelled MS0-MS4 which seem to control the
+ memory address, and another three labelled IO0-IO2 which seem to
+ control the base I/O address of the card.
+
+ This was difficult to test by trial and error, and the I/O addresses
+ are in a weird order. This was tested by setting the DIP switches,
+ rebooting the computer, and attempting to load ARCETHER at various
+ addresses (mostly between 0x200 and 0x400). The address that caused
+ the red transmit LED to blink, is the one that I thought works.
+
+ Also, the address 0x3D0 seem to have a special meaning, since the
+ ARCETHER packet driver loaded fine, but without the red LED
+ blinking. I don't know what 0x3D0 is for though. I recommend using
+ an address of 0x300 since Windows may not like addresses below
+ 0x300.
+
+ IO Switch No.
+ 210 I/O address
+ -------------------------------
+ 111 0x260
+ 110 0x290
+ 101 0x2E0
+ 100 0x2F0
+ 011 0x300
+ 010 0x350
+ 001 0x380
+ 000 0x3E0
+
+ The memory switches set a reserved address space of 0x1000 bytes
+ (0x100 segment units, or 4k). For example if I set an address of
+ 0xD000, it will use up addresses 0xD000 to 0xD100.
+
+ The memory switches were tested by booting using QEMM386 stealth,
+ and using LOADHI to see what address automatically became excluded
+ from the upper memory regions, and then attempting to load ARCETHER
+ using these addresses.
+
+ I recommend using an arcnet memory address of 0xD000, and putting
+ the EMS page frame at 0xC000 while using QEMM stealth mode. That
+ way, you get contiguous high memory from 0xD100 almost all the way
+ the end of the megabyte.
+
+ Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
+ on my card. It could be malfunctioning on my card. Experiment with
+ it ON first, and if it doesn't work, set it to OFF. (It may be a
+ modifier for the 0x200 bit?)
+
+ MS Switch No.

+Setting the Node ID
+-------------------
+
+The eight switches in SW2 are used to set the node ID. Each node attached
+to the network must have an unique node ID which must be diffrent from 0.
+Switch 1 (ID0) serves as the least significant bit (LSB).
+
+The node ID is the sum of the values of all switches set to "1"
+These values are:
+
+ Switch | Label | Value
+ -------|-------|-------

+
+Setting the I/O Base Address
+----------------------------
+
+The last three switches in switch block SW1 are used to select one
+of eight possible I/O Base addresses using the followig table
+
+
+ Switch | Hex I/O
+ 6 7 8 | Address
+ ------------|--------
+ ON ON ON | 260
+ OFF ON ON | 290
+ ON OFF ON | 2E0 (Manufactor's default)
+ OFF OFF ON | 2F0
+ ON ON OFF | 300
+ OFF ON OFF | 350
+ ON OFF OFF | 380
+ OFF OFF OFF | 3E0
+
+
+Setting the Base Memory (RAM) buffer Address
+--------------------------------------------
+
+The memory buffer (RAM) requires 2K. The base of this buffer can be
+located in any of eight positions. The address of the Boot Prom is
+memory base + 8K or memory base + 0x2000.
+Switches 1-5 of switch block SW1 select the Memory Base address.
+
+ Switch | Hex RAM | Hex ROM
+ 1 2 3 4 5 | Address | Address *)
+ --------------------|---------|-----------
+ ON ON ON ON ON | C0000 | C2000
+ ON ON OFF ON ON | C4000 | C6000
+ ON ON ON OFF ON | CC000 | CE000
+ ON ON OFF OFF ON | D0000 | D2000 (Manufactor's default)
+ ON ON ON ON OFF | D4000 | D6000
+ ON ON OFF ON OFF | D8000 | DA000
+ ON ON ON OFF OFF | DC000 | DE000
+ ON ON OFF OFF OFF | E0000 | E2000
+
+*) To enable the Boot ROM install the jumper JP1
+
+Note: Since the switches 1 and 2 are always set to ON it may be possible
+ that they can be used to add an offset of 2K, 4K or 6K to the base
+ address, but this feature is not documented in the manual and I
+ haven't testet it yet.
+
+
+Setting the Interrupt Line
+--------------------------
+

+Setting the Node ID
+-------------------
+
+The eight switches in SW2 are used to set the node ID. Each node attached
+to the network must have an unique node ID which must be diffrent from 0.
+Switch 1 (ID0) serves as the least significant bit (LSB).
+
+The node ID is the sum of the values of all switches set to "1"
+These values are:
+
+ Switch | Label | Value
+ -------|-------|-------
+ 1 | ID0 | 1
+ 2 | ID1 | 2

+
+NONAME 16-BIT ARCNET
+====================
+
+The manual of my 8-Bit NONAME ARCnet Card contains another description
+of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
+because there are missing two pages in the manual booklet. (The table
+of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
+the booklet there is a diffrent way of counting ... 2-9, 2-10, A-1,
+(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
+Also the picture of the board layout is not as good as the picture of
+8-Bit card, because there isn't any letter like "SW1" written to the
+picture.
+Should somebody have such a board, please feel free to complete this
+description or to send a mail to me!

+Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
+switches.
+
+Setting the jumpers to ON means connecting the upper two pins, off the bottom
+two - or - in case of IRQ setting, connecting none of them at all.
+
+Setting the Node ID
+-------------------
+
+The eight switches in SW2 are used to set the node ID. Each node attached
+to the network must have an unique node ID which must be diffrent from 0.
+Switch 1 (ID0) serves as the least significant bit (LSB).
+
+Setting one of the switches to Off means "1", On means "0".
+
+The node ID is the sum of the values of all switches set to "1"
+These values are:
+
+ Switch | Label | Value
+ -------|-------|-------
+ 1 | ID0 | 1
+ 2 | ID1 | 2
+ 3 | ID2 | 4
+ 4 | ID3 | 8
+ 5 | ID4 | 16
+ 6 | ID5 | 32
+ 7 | ID6 | 64
+ 8 | ID7 | 128
+
+Some Examples:
+
+ Switch | Hex | Decimal
+ 8 7 6 5 4 3 2 1 | Node ID | Node ID
+ ----------------|---------|---------
+ 0 0 0 0 0 0 0 0 | not allowed
+ 0 0 0 0 0 0 0 1 | 1 | 1
+ 0 0 0 0 0 0 1 0 | 2 | 2
+ 0 0 0 0 0 0 1 1 | 3 | 3
+ . . . | |
+ 0 1 0 1 0 1 0 1 | 55 | 85
+ . . . | |
+ 1 0 1 0 1 0 1 0 | AA | 170
+ . . . | |
+ 1 1 1 1 1 1 0 1 | FD | 253
+ 1 1 1 1 1 1 1 0 | FE | 254
+ 1 1 1 1 1 1 1 1 | FF | 255
+
+
+Setting the I/O Base Address
+----------------------------
+
+The last three switches in switch block SW1 are used to select one
+of eight possible I/O Base addresses using the followig table
+
+
+ Switch | Hex I/O
+ 6 7 8 | Address
+ ------------|--------
+ ON ON ON | 260
+ OFF ON ON | 290
+ ON OFF ON | 2E0 (Manufactor's default)
+ OFF OFF ON | 2F0
+ ON ON OFF | 300
+ OFF ON OFF | 350
+ ON OFF OFF | 380
+ OFF OFF OFF | 3E0
+
+
+Setting the Base Memory (RAM) buffer Address
+--------------------------------------------
+
+The memory buffer (RAM) requires 2K. The base of this buffer can be
+located in any of eight positions. The address of the Boot Prom is
+memory base + 0x2000.
+Jumpers 3-5 of jumper block SW1 select the Memory Base address.
+
+ Switch | Hex RAM | Hex ROM
+ 1 2 3 4 5 | Address | Address *)
+ --------------------|---------|-----------
+ ON ON ON ON ON | C0000 | C2000
+ ON ON OFF ON ON | C4000 | C6000
+ ON ON ON OFF ON | CC000 | CE000
+ ON ON OFF OFF ON | D0000 | D2000 (Manufactor's default)
+ ON ON ON ON OFF | D4000 | D6000
+ ON ON OFF ON OFF | D8000 | DA000
+ ON ON ON OFF OFF | DC000 | DE000
+ ON ON OFF OFF OFF | E0000 | E2000
+
+*) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
+
+The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM addres.
+
+Setting the Interrupt Line
+--------------------------
+
+Jumpers 1-5 of the jumper block SW3 controll the IRQ level.
+
+ Jumper | IRQ
+ 1 2 3 4 5 |
+ ----------------------------
+ ON OFF OFF OFF OFF | 2
+ OFF ON OFF OFF OFF | 3
+ OFF OFF ON OFF OFF | 4
+ OFF OFF OFF ON OFF | 5
+ OFF OFF OFF OFF ON | 7
+
+
+Setting the Timeout Parameters
+------------------------------
+
+The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
+parameters. These two jumpers are normally left in the OFF position.

- About the jumpers: On my PC130 there is one more jumper, located near the
- cable-connector and it's for changing to star or bus topology;
- closed: star - open: bus
- On the PC500 are some more jumper-pins, one block labled with RX,PDN,TXI
- and another with ALE,LA17,LA18,LA19 these are undocumented..

-
-Quick Briefing:
----------------
-
-All ARCnet cards should have a total of four different settings:
-
- - the I/O address: this is the "port" your ARCnet card is on. Probed
- values, as of v0.14, are only from 0x200 through 0x3F0. (If your card
- has additional ones, which is possible, please tell me.) This should not
- be the same as any other device on your system. According to a doc I
- got from Novell, MS Windows prefers values of 0x300 or more, eating
- netconnections on my system otherwise.
- - Avery's favourite: 0x300.
-
- - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
- on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15. Make
- sure this is different from any other card on your system. Note that
- IRQ2 is the same as IRQ9, as far as Linux is concerned.
- - Avery's favourite: IRQ2.
-
- - the memory address: Unlike most cards, ARCnets use "shared memory" for
- copying buffers around. Make SURE it doesn't conflict with any other
- used memory in your system!
- A0000 - VGA graphics memory (ok if you don't have VGA)
- B0000 - Monochrome text mode
- C0000 \ One of these is your VGA BIOS - usually C0000.
- E0000 /
- F0000 - System BIOS
-
- Anything less than 0xA0000 is, well, a BAD idea since it isn't above
- 640k.
- - Avery's favourite: 0xD0000
-
- - the station address: Every ARCnet card has its own "unique" network
- address from 0 to 255. Unlike ethernet, you can set this address
- yourself. Since it's only 8 bits, you can only have 254 ARCnet cards on
- a network. DON'T use 0 or 255, since these are reserved. (although neat
- stuff will probably happen if you DO use them). By the way, if you
- haven't already guessed, don't set this the same as any other ARCnet on
- your network!
- - Avery's favourite: 3 and 4. Not that it matters.

-PC100, PC110, PC120, PC130 (8-bit cards)
-PC500, PC600 (16-bit cards)
----------------------------------
- - mainly from Avery Pennarun <apenwarr@foxnet.net>. Values depicted are
- from Avery's setup.
- - special thanks to Timo Hilbrink <timoh@xs4all.nl> for noting that PC120,
- 130, 500, and 600 all have the same switches as Avery's PC100.
- PC500/600 have several extra, undocumented pins though. (?)
- - PC110 settings were verified by Stephen A. Wood <saw@cebaf.gov>
- - On the other hand, John Edward Bauer <jbauer@badlands.NoDak.edu> said
- the PC110 settings are all wrong. In his case, you need to switch all
- the 1's with 0's. If you're having problems, try that.
- - Also, the JP- and S-numbers probably don't match your card exactly. Try
- to find jumpers/switches with the same number of settings - it's
- probably more reliable.

-*) To enable the 8K Boot PROM install the jumper ROM.
- The default is jumper ROM not installed.
-
-
-Setting the Timeouts and Interrupt
-----------------------------------
-
-The jumpers labeled EXT1 and EXT2 are used to determine the timeout
-parameters. These two jumpers are normally left open.
-Refer to the COM9026 Data Sheet for alternate configurations.
-
-To select a hardware interrupt level set one (only one!) of the jumpers
-IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufactor's default is IRQ2.
-
-
-Configuring the PC130E for Star or Bus Topology
------------------------------------------------
-
-The single jumper labeled STAR is used to configure the PC130E board for
-star or bus topology.
-When the jumper is installed, the board may be used in a star network, when
-it is removed, the board can be used in a bus topology.
-
-
-Diagnostic LEDs
----------------
-
-Two diagnostic LEDs are visible on the rear bracket of the board.
-The green LED monitors the network activity: the red one shows the
-board activity:
-
- Green | Status Red | Status
- -------|------------------- ---------|-------------------
- on | normal activity flash/on | data transfer
- blink | reconfiguration off | no data transfer;
- off | defectiv board or | incorect memory or
- | node ID is zero | I/O address

-Setting the Node ID
--------------------
-
-The eight switches in group SW3 are used to set the node ID. Each node
-attached to the network must have an unique node ID which must be
-diffrent from 0.
-Switch 1 serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:
-

-
-Setting the Interrupt
----------------------
-
-Switches seven through ten of switch group SW1 are used to select the
-interrupt level. The interrupt level is binary coded, so selections
-from 0 to 15 would be possible, but only the following eight values will
-be supported: 3, 4, 5, 7, 9, 10, 11, 12.
-
- Switch | IRQ
- 10 9 8 7 |
- ---------|--------
- 0 0 1 1 | 3
- 0 1 0 0 | 4
- 0 1 0 1 | 5
- 0 1 1 1 | 7
- 1 0 0 1 | 9 (=2) (default)
- 1 0 1 0 | 10
- 1 0 1 1 | 11
- 1 1 0 0 | 12
-
-
-Setting the Timeouts
---------------------
-
-The two jumpers JP2 (1-4) are used to determine the timeout parameters.
-These two jumpers are normally left open.
-Refer to the COM9026 Data Sheet for alternate configurations.
-
-
-Configuring the PC500 for Star or Bus Topology
-----------------------------------------------
-
-The single jumper labeled JP6 is used to configure the PC500 board for
-star or bus topology.
-When the jumper is installed, the board may be used in a star network, when
-it is removed, the board can be used in a bus topology.
-
-
-Diagnostic LEDs
----------------
-
-Two diagnostic LEDs are visible on the rear bracket of the board.
-The green LED monitors the network activity: the red one shows the
-board activity:
-
- Green | Status Red | Status
- -------|------------------- ---------|-------------------
- on | normal activity flash/on | data transfer
- blink | reconfiguration off | no data transfer;
- off | defectiv board or | incorect memory or
- | node ID is zero | I/O address

-PDI507 (16-bit card)
---------------------
- - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by
- Avery)
- - Send questions/suggestions/etc about this text to Mark.
-
-Jumpers:
-
- There is a jumper array at the bottom of the card, near the edge
- connector. This array is labelled J1. They control the IRQs and
- something else. Put only one jumper on the IRQ pins.
-
- IRQ2 - Use IRQ 2 (same as IRQ 9 as far as software is concerned)
- IRQ3 - Use IRQ 3 (used by COM2 or COM4 serial port if either exists)
- IRQ4 - Use IRQ 4 (used by COM1 or COM3 serial port if either exists)
- IRQ5 - Use IRQ 5 (used by LPT2 parallel port if one exists)
- IRQ6 - Use IRQ 6 (used by Floppy Disk Controller if one exists)
- IRQ7 - Use IRQ 7 (used by LPT1 parallel port if one exists)
-
-[Avery's note: This "unknown" set of two jumpers appears to be on all
-ARCnet cards by SMC as well. Putting jumpers on them seems to affect the
-status register, but only for the two "reserved" bits, ETS1 and ETS2. Any
-further information is welcome.]
-
- ET1 - What is this? (Not tested, no jumper put on it)
- ET2 - What is this? (Not tested, no jumper put on it)
-
- There is a J2 jumper on two pins. A jumper should be put on them,
- since it was already there when I got the card. I don't know what
- this jumper is for though.
-
- There is a two-jumper array for J3. I don't know what it is for,
- but there were already two jumpers on it when I got the card. It's
- a six pin grid in a two-by-three fashion. The jumpers were
- configured as follows:
-
- .-------.
- o | o o |
- :-------: ------> Accessible end of card with connectors
- o | o o | in this direction ------->
- `-------'
-
- There is also a J4 jumper on two pins. A jumper should be put on
- them, since it was already there when I got the card. I don't know
- what this jumper is for though.
-
-
-DIP Switches:
-
- The dipswitches accessible on the accessible end of the card while
- it is installed, is used to set the arcnet address. There are 8
- switches. Use an address from 1 to 254.
-
- Switch No.
- 12345678 Arcnet address
- -----------------------------------------
- 00000000 FF (Don't use this!)
- 00000001 FE
- 00000010 FD
- ....
- 11111101 2
- 11111110 1
- 11111111 0 (Don't use this!)
-
- There is another dipswitch array of 8 switches at the top of the
- card. There are five labelled MS0-MS4 which seem to control the
- memory address, and another three labelled IO0-IO2 which seem to
- control the base I/O address of the card.
-
- This was difficult to test by trial and error, and the I/O addresses
- are in a weird order. This was tested by setting the DIP switches,
- rebooting the computer, and attempting to load ARCETHER at various
- addresses (mostly between 0x200 and 0x400). The address that caused
- the red transmit LED to blink, is the one that I thought works.
-
- Also, the address 0x3D0 seem to have a special meaning, since the
- ARCETHER packet driver loaded fine, but without the red LED
- blinking. I don't know what 0x3D0 is for though. I recommend using
- an address of 0x300 since Windows may not like addresses below
- 0x300.
-
- IO Switch No.
- 210 I/O address
- -------------------------------
- 111 0x260
- 110 0x290
- 101 0x2E0
- 100 0x2F0
- 011 0x300
- 010 0x350
- 001 0x380
- 000 0x3E0
-
- The memory switches set a reserved address space of 0x1000 bytes
- (0x100 segment units, or 4k). For example if I set an address of
- 0xD000, it will use up addresses 0xD000 to 0xD100.
-
- The memory switches were tested by booting using QEMM386 stealth,
- and using LOADHI to see what address automatically became excluded
- from the upper memory regions, and then attempting to load ARCETHER
- using these addresses.
-
- I recommend using an arcnet memory address of 0xD000, and putting
- the EMS page frame at 0xC000 while using QEMM stealth mode. That
- way, you get contiguous high memory from 0xD100 almost all the way
- the end of the megabyte.
-
- Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
- on my card. It could be malfunctioning on my card. Experiment with
- it ON first, and if it doesn't work, set it to OFF. (It may be a
- modifier for the 0x200 bit?)
-
- MS Switch No.
- 43210 Memory address
- --------------------------------
- 00001 0xE100 (guessed - was not detected by QEMM)
- 00011 0xE000 (guessed - was not detected by QEMM)
- 00101 0xDD00
- 00111 0xDC00
- 01001 0xD900
- 01011 0xD800
- 01101 0xD500
- 01111 0xD400
- 10001 0xD100
- 10011 0xD000
- 10101 0xCD00
- 10111 0xCC00
- 11001 0xC900 (guessed - crashes tested system)
- 11011 0xC800 (guessed - crashes tested system)

-Setting the Node ID
--------------------
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must be diffrent from 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:
-
- Switch | Label | Value
- -------|-------|-------
- 1 | ID0 | 1
- 2 | ID1 | 2

-
-Setting the I/O Base Address
-----------------------------
-
-The last three switches in switch block SW1 are used to select one
-of eight possible I/O Base addresses using the followig table
-
-
- Switch | Hex I/O
- 6 7 8 | Address
- ------------|--------
- ON ON ON | 260
- OFF ON ON | 290
- ON OFF ON | 2E0 (Manufactor's default)
- OFF OFF ON | 2F0
- ON ON OFF | 300
- OFF ON OFF | 350
- ON OFF OFF | 380
- OFF OFF OFF | 3E0
-
-
-Setting the Base Memory (RAM) buffer Address
---------------------------------------------
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of eight positions. The address of the Boot Prom is
-memory base + 8K or memory base + 0x2000.
-Switches 1-5 of switch block SW1 select the Memory Base address.
-
- Switch | Hex RAM | Hex ROM
- 1 2 3 4 5 | Address | Address *)
- --------------------|---------|-----------
- ON ON ON ON ON | C0000 | C2000
- ON ON OFF ON ON | C4000 | C6000
- ON ON ON OFF ON | CC000 | CE000
- ON ON OFF OFF ON | D0000 | D2000 (Manufactor's default)
- ON ON ON ON OFF | D4000 | D6000
- ON ON OFF ON OFF | D8000 | DA000
- ON ON ON OFF OFF | DC000 | DE000
- ON ON OFF OFF OFF | E0000 | E2000
-
-*) To enable the Boot ROM install the jumper JP1
-
-Note: Since the switches 1 and 2 are always set to ON it may be possible
- that they can be used to add an offset of 2K, 4K or 6K to the base
- address, but this feature is not documented in the manual and I
- haven't testet it yet.
-
-
-Setting the Interrupt Line
---------------------------
-
-To select a hardware interrupt level install one (only one!) of the jumpers
-JP2, JP3, JP4, JP5, JP6. JP2 is the default.
-
- Jumper | IRQ

-NONAME 16-BIT ARCNET
-====================
-
-The manual of my 8-Bit NONAME ARCnet Card contains another description
-of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
-because there are missing two pages in the manual booklet. (The table
-of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
-the booklet there is a diffrent way of counting ... 2-9, 2-10, A-1,
-(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
-Also the picture of the board layout is not as good as the picture of
-8-Bit card, because there isn't any letter like "SW1" written to the
-picture.
-Should somebody have such a board, please feel free to complete this
-description or to send a mail to me!

-Setting the Node ID
--------------------
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must be diffrent from 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-Setting one of the switches to Off means "1", On means "0".
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:

-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of eight positions. The address of the Boot Prom is
-memory base + 0x2000.
-Jumpers 3-5 of jumper block SW1 select the Memory Base address.
-
- Switch | Hex RAM | Hex ROM
- 1 2 3 4 5 | Address | Address *)

You can also add a num=1, num=2 etc for additional arcnet cards that will
use arc1, arc2 etc for their device names (instead of the default, arc0).

+If you build your kernel with ARCnet support included, it should probe for
+your card automatically when you boot.
+
+Go read the NET-2-HOWTO and ETHERNET-HOWTO for Linux; they should be
available where you picked up this driver. Think of your ARCnet as a
souped-up (or down, as the case may be) ethernet card.
LAN Manager and Windows for Workgroups: These programs use protocols that
are incompatible with the internet standard. They try to pretend
the cards are ethernet, and confuse everyone else on the network.
- However, v1.93 ALPHA and later of the Linux ARCnet driver support
- this protocol via the 'arc0e' device. After setting up arc0 as
- usual, ifconfig and set up routes to your ethernet-encap hosts
- through arc0e. There may be non-Microsoft products that support
- this protocol as well, so it was changed in 1.93 ALPHA from arc0w
- to arc0e.
+
+ However, v2.00 of the Linux ARCnet driver supports this protocol via
+ the 'arc0e' device. See the section on "Multiprotocol Support" for
+ more information.
Using the freeware Samba server and clients for Linux, you can now
interface quite nicely with TCP/IP-based WfWg or Lan Manager
- networks. In addition, the Linux host can be used as a router
- between the standard and WfWg protocols, so hosts that could
- previously never talk to each other should now be able to.

+Windows 95: Tools are included with Win95 that let you use either the LANMAN

+ ARCnet packets. If you use ODI, you'll need to use the 'arc0'
+ device with Linux. If you use NDIS, then try the 'arc0e' device.
+ See the "Multiprotocol Support" section below if you need arc0e,
+ you're completely insane, and/or you need to build some kind of
+ hybrid network that uses both encapsulation types.

IBM's "TCP/IP for OS/2" or "Warp Connect" packages. However,

+
+Using Multiprotocol ARCnet
+--------------------------
+The ARCnet driver v2.00 supports two protocols, each on its own "virtual
+network device":
+ arc0 - RFC1201 protocol, the official internet standard which just
+ happens to be 100% compatible with Novell's TRXNET driver.
+ Version 1.00 of the ARCnet driver _only_ supported this
+ protocol. arc0 is the faster of the two protocols, and
+ allows larger packets to be used because it supports RFC1201
+ "packet splitting" operations. Unless you have a specific
+ need to use a different protocol, I highly suggest that you
+ stick with this one.
+
+ arc0e - "Ethernet-Encapsulation" which sends packets over ARCnet
+ that are actually a lot like Ethernet packets, including the
+ 6-byte hardware addresses. This protocol is compatible with
+ Microsoft's NDIS ARCnet driver, like the one in WfWg and
+ LANMAN. Because the MTU of 493 is actually smaller than the
+ one "required" by TCP/IP (576), there is a chance that some
+ network operations will not work properly. The Linux TCP/IP
+ layer can compensate in most cases, however, by
+ automatically fragmenting the TCP/IP packets to make them
+ fit. arc0e also works slightly more slowly than arc0, for
+ reasons yet to be determined. (Probably it's the smaller
+ MTU that does it)
+
+The arc0e device is created automatically when you first 'ifconfig' the arc0
+device. To actually use arc0e, though, you need to 'ifconfig' it as well.
+There are a number of ways you can set up your network then:
+
+
+1. Single Protocol.
+
+ This is the simplest way to configure your network: use just one of the
+ two available protocols. As mentioned above, it's a good idea to use
+ only arc0 unless you have a good reason (like some other software, ie.
+ WfWg, that only works with arc0e).
+
+ If you need only arc0, then the following commands should get you going:
+ ifconfig arc0 MY.IP.ADD.RESS
+ route add MY.IP.ADD.RESS arc0
+ route add SUB.NET.ADD.RESS arc0
+ [etc]
+
+ If you need arc0e (and only arc0e), it's a little different:
+ ifconfig arc0 up /* the IP address doesn't matter on arc0 */
+ ifconfig arc0e MY.IP.ADD.RESS
+ route add MY.IP.ADD.RESS arc0e
+ route add SUB.NET.ADD.RESS arc0e
+
+
+2. More than one protocol on the same wire.
+
+ Now things start getting confusing. To even try it, you may need to be
+ partly crazy. Here's what *I* did. :)
+
+ I have three computers on my home network; two Linux boxes (which prefer
+ RFC1201 protocol), and one XT that can't run Linux but runs the free
+ Microsoft LANMAN Client instead.
+
+ Worse, one of the Linux computers (freedom) also has a modem and acts as
+ a router to my information provider. The other Linux box (insight) also
+ has its own IP address and needs to use freedom as its default gateway.
+ The XT (patience), however, does not have its own internet IP address and
+ so I assigned it one on a "private subnet" (as defined by RFC1597).
+
+ To start with, take a simple network with just insight and freedom.
+ Insight needs to:
+ - talk to freedom via RFC1201 (arc0) protocol, because I like it
+ more and it's faster.
+ - use freedom as its internet gateway.
+
+ That's pretty easy to do. Set up insight like this:
+ ifconfig arc0 insight
+ route add insight arc0
+ route add freedom arc0 /* I would use the subnet here (like I said
+ to to in "single protocol" above),
+ but the rest of the subnet
+ unfortunately lies across the PPP
+ link on freedom, which confuses
+ things. */
+ route add default gw freedom
+
+ And freedom gets configured like so:
+ ifconfig arc0 freedom
+ route add freedom arc0
+ route add insight arc0
+ /* and default gateway is configured by PPP */
+
+ Great, now insight talks to freedom directly on arc0, and sends packets
+ to the internet through freedom. If you didn't know how to do the above,
+ you should probably stop reading this section now because it only gets
+ worse.
+
+ Now, how do I add patience into the network? It will be using LANMAN
+ Client, which means I need the arc0e device. It needs to be able to talk
+ to both insight and freedom, and also use freedom as a gateway to the
+ internet. (Recall that patience has a "private IP address" which won't
+ work on the internet; that's okay, I configured Linux IP masquerading on
+ freedom for this subnet).
+
+ So patience (necessarily; I don't have another IP number from my
+ provider) has an IP address on a different subnet than freedom and
+ insight, but needs to use freedom as an internet gateway. Worse, most
+ DOS networking programs, including LANMAN, have braindead networking
+ schemes that rely completely on the netmask and a 'default gateway' to
+ determine how to route packets. This means that to get to freedom or
+ insight, patience WILL send through its default gateway, regardless of
+ the fact that both freedom and insight (courtesy of the arc0e device)
+ could understand a direct transmission.
+
+ I compensate by giving freedom an extra IP address - aliased 'gatekeeper'
+ - that is on my private subnet, the same subnet that patience is on. I
+ then define gatekeeper to be the default gateway for patience.
+
+ To configure freedom (in addition to the commands above):
+ ifconfig arc0e gatekeeper
+ route add gatekeeper arc0e
+ route add patience arc0e
+
+ This way, freedom will send all packets for patience through arc0e,
+ giving its IP address as gatekeeper (on the private subnet). When it
+ talks to insight or the internet, it will use its "freedom" internet IP
+ address.
+
+ You will notice that we haven't configured the arc0e device on insight.
+ This would work, but is not really necessary, and would require me to
+ assign insight another special IP number from my private subnet. Since
+ both insight and patience are using freedom as their default gateway, the
+ two can already talk to each other.
+
+ It's quite fortunate that I set things up like this the first time
+ through (cough cough) because it's really handy when I boot insight into
+ DOS. There, it runs the Novell ODI protocol stack, which only works with
+ RFC1201 ARCnet. In this mode it would be impossible for insight to
+ communicate directly with patience, since the Novell stack is
+ incompatible with Microsoft's Ethernet-Encap. Without changing any
+ settings on freedom or patience, I simply set freedom as the default
+ gateway for insight (now in DOS, remember) and all the forwarding happens
+ "automagically" between the two hosts that would normally not be able to
+ communicate at all.
+
+ For those who like diagrams, I have created two "virtual subnets" on the
+ same physical ARCnet wire. You can picture it like this:
+
+
+ [RFC1201 NETWORK] [ETHER-ENCAP NETWORK]
+ (registered internet subnet) (RFC1597 private subnet)
+
+ (IP Masquerade)

It works: what now?

Note that the debug level is (as of v1.90 ALPHA) a binary combination of

resulting in debug level 15.

+0. Installation of the package
+==============================
+
+Run SCC-Install. If one (or more) of the patches fails PLEASE consult
+chapter 2 (and READ IT of course!)
+
+
+
+1. Initialization and attachment of the channels
+================================================
+
+To use the driver, 3 steps must be performed:
+
+ 1. Global initialization of the driver in the kernel
+ 2. Setup of parameters with sccinit
+ 2. Attachment of each channel in the packet software
+
+The global initialization is needed to reset all SCCs and to
+install a common interrupt handler. Also, the hardware addresses
+of the chips are defined in this step. In the second step, each
+channel is set up for the intended use.
+
+
+
+1.1. Initialization
+===================
+
+Initialization of the hardware is performed by setting the defines and
+variables in the file "/linux/drivers/char/scc_config.h". You can change
+a number of parameters.

+The channel number ranges from 0 to (2 * Nchips) - 1,
+where Nchips is the number of chips.
+
+The crystal clock is specified as 4.9152 MHz. Other frequencies
+can be used, and this parameter should be adjusted accordingly.
+
+
+You can define your scc type with Board
+
+ SCC type value
+ ---------------------------------
+ PA0HZP SCC card PA0HZP
+ EAGLE card EAGLE
+ PC100 card PC100
+ PRIMUS-PC (DG9BL) card PRIMUS
+ BayCom (U)SCC card BAYCOM
+
+
+NOTE:
+=====
+
+If you only know the parameters for the PE1CHL driver for DOS,
+run gencfg. It will generate the correct port addresses (I hope).
+Its parameters are exactly the same as the ones you use with
+the "attach scc" command in net, except that the string "init" must
+not appear. Example:
+
+gencfg 2 0x150 4 2 0 1 0x168 9 4915200
+
+will print a short form of scc_config.h for the OptoSCC to stdout.
+("short" <=> few comments).
+
+gencfg 2 0x300 2 4 5 -4 0 7 4915200 0x10
+
+does the same for the BayCom USCC card. I my opinion it is much easier
+to edit scc_config.h...
+
+
+1.2 initializing the driver on bootup
+=====================================
+
+
+To setup a number parameters you must run /sbin/sccinit from one
+of your rc.*-files. This has to be done BEFORE the start of
+NET or the ax25attach. Sccinit reads the file /etc/z8530drv.rc
+and sets the MODEM and KISS parameters. A sample file is
+delivered with this package. Change it to your needs:
+
+Each channel definition is divided into three sections. An
+example for /dev/sc1:
+
+# DEVICE
+
+device /dev/sc1 # the device for the following params
+
+# MODEM
+
+speed 1200 # the default baudrate
+clock dpll # clock source:
+ # dpll = normal halfduplex operation
+ # external = MODEM provides own Rx/Tx clock
+ # divider = use fullduplex divider if
+ # installed (1)
+mode nrzi # HDLC encoding mode
+ # nrzi = 1k2 MODEM, G3RUH 9k6 MODEM
+ # nrz = DF9IC 9k6 MODEM
+# KISS (Layer 1)
+
+txdelay 36 # (see chapter 1.4)
+persist 64
+slot 8
+tail 8
+fulldup 0
+wait 12
+min 3
+maxkey 7
+idle 3
+maxdef 120
+group 0
+txoff off
+softdcd on
+slip off
+
+The order WITHIN these sections is unimportant. The order OF these
+sections IS important. The MODEM parameters are set with the first
+recognized KISS paramer...
+
+Please note that you can initialize the board only once after boot.
+You can change all paramters but "mode" and "clock" later with the
+Sccparam program or through KISS. Just to avoid securety holes...
+
+(1) this divider is usually mounted on the SCC-PBC (PA0HZP) or not
+ present at all (BayCom). It feeds back the output of the DPLL
+ (digital pll) as transmit clock. Using this mode without a divider
+ installed will normally result in keying the transceiver until
+ maxkey expires --- of course without sending anything (useful).
+
+
+1.3. Attach commands
+====================
+
+When the linux has startup, the SCC driver has been initialized,
+you can attach the channels in your packet software. This is done
+by open the scc devices by using the attach asy command.
+The SCC-drivers emulates the scc devices as serial asy ports,
+this means e.g. that the baudrate can be set in the attach command.
+
+
+Example Wampes:
+
+#############################################################################################
+# Wampes device attach
+# NOTE: Interfacename and the device must be the same!!
+# Usage: attach asy 0 0 slip|vjslip|ax25ui|ax25i|nrs|kissui <label> 0 <mtu> <speed> [ip_addr]
+#
+attach asy 0 0 kissi sc1 256 256 1200 # Attach SCC channel 1 in 1200 baud
+attach asy 0 0 kissi sc2 256 256 1200 # Attach SCC channel 2 in 1200 baud
+attach asy 0 0 kissui sc3 256 256 38400 # Attach SCC channel 3 in 38400 baud
+attach asy 0 0 kissui sc4 256 256 9600 # Attach SCC channel 4 in 9600 baud
+# ^
+# for WAMPES 921229 use here: ax25
+#
+
+Example JNOS:
+
+############################################
+# JNOS device attach
+#
+#attach asy sc1 0 ax25 sc1 256 256 1200
+#attach asy sc2 0 ax25 sc2 256 256 1200
+#attach asy sc3 0 ax25 sc3 256 256 300
+#attach asy sc4 0 ax25 sc4 256 256 4800
+#
+#
+
+
+It allows AX.25 communication without a TNC. Only a MODEM is
+needed. The parameters have the same meaning as in KISS mode.
+In fact, the AX.25 mode is emulating an extended KISS TNC, so
+the same commands can be used to set the parameters of the
+interface (see below).
+
+To be able to run fullduplex using an SCC in AX.25 mode, an
+external divider must be available, that divides the baudrate
+generator clock available on the TRxC pin by 32, and puts the
+resulting signal on the RTxC pint of the same channel of the SCC.
+Such a divider is not necessary for normal CSMA packet radio
+operation, but interrupt overhead is slightly reduced if you
+still install it.
+
+
+
+1.4. Displaying SCC Parameters:
+===============================
+
+Once a SCC channel has been attached, the parameter settings and
+some statistic information can be shown using the param program:
+
+dl1bke-u:~$ sccstat /dev/sc1
+
+Parameters:
+
+speed : 1200 baud
+txdelay : 36
+persist : 255
+slottime : 0
+txtail : 8
+fulldup : 1
+waittime : 12
+mintime : 3 sec
+maxkeyup : 7 sec
+idletime : 3 sec
+maxdefer : 120 sec
+group : 0x00
+txoff : off
+softdcd : on
+SLIP : off
+
+Status:
+
+HDLC Z8530 Interrupts Queues
+-----------------------------------------------------------------------
+Sent : 273 RxOver : 0 RxInts : 125074 RxQueue : 0
+Received : 1095 TxUnder: 0 TxInts : 4684 TxQueue : 0
+RxErrors : 1591 ExInts : 11776
+KissErrors : 0 SpInts : 1503 NoSpace : 0
+Tx State : idle
+
+Memory allocated:
+
+Total : 1
+RxAlloc: 0
+TxAlloc: 1
+
+
+The status info shown is:
+
+Sent - number of frames transmitted
+Received - number of frames received
+RxErrors - number of receive errors (CRC, ABORT)
+KissErrors - number of KISS errors (should be zero...)
+Tx State - status of the Tx interrupt handler: idle/busy/active/tail (2)
+RxOver - number of receiver overruns
+TxUnder - number of transmitter underruns
+RxInts - number of receiver interrupts
+TxInts - number of transmitter interrupts
+EpInts - number of receiver special condition interrupts
+SpInts - number of external/status interrupts
+RxQueue - number of received packets enqueued for this channel
+TxQueue - number of packets enqueued for Tx
+NoSpace - number of times the receiver buffer pool was found empty
+
+
+An overrun is abnormal. If lots of these occur, the product of
+baudrate and number of interfaces is too high for the processing
+power of you computer. If "Space" errors occur, specify a higher
+number of buffers in the "scc.h" file.
+
+
+1.5 Setting Parameters
+======================
+
+
+The setting of parameters of the emulated KISS TNC is done in the
+same way in the SCC driver. You can change parameters by using
+the command param in NET or NOS
+
+ param <iface> <paramname> <value>
+
+or use the program "sccparam":
+
+ sccparam <device> <paramname> <decimal-|hexadecimal value>
+
+You can change the following parameters:
+
+param : value
+------------------------
+speed : 1200
+txdelay : 36
+persist : 255
+slottime : 0
+txtail : 8
+fulldup : 1
+waittime : 12
+mintime : 3
+maxkeyup : 7
+idletime : 3
+maxdefer : 120
+group : 0x00
+txoff : off
+softdcd : on
+SLIP : off
+
+
+The parameters have the following meaning:
+
+speed:
+ The baudrate on this channel in bits/sec
+
+ Example: sccparam /dev/sc4 speed 9600
+
+txdelay:
+ The delay (in units of 10ms) after keying of the
+ transmitter, until the first byte is sent. This is usually
+ called "TXDELAY" in a TNC. When 0 is specified, the driver
+ will just wait until the CTS signal is asserted. This
+ assumes the presence of a timer or other circuitry in the
+ MODEM and/or transmitter, that asserts CTS when the
+ transmitter is ready for data.
+ A normal value of this parameter is 30-36.
+
+ Example: sccparam /dev/sc1 txd 20
+
+persist:
+ This is the probability that the transmitter will be keyed
+ when the channel is found to be free. It is a value from 0
+ to 255, and the probability is (value+1)/256. The value
+ should be somewhere near 50-60, and should be lowered when
+ the channel is used more heavily.
+
+ Example: sccparam /dev/sc3 persist 20
+
+slottime:
+ This is the time between samples of the channel. It is
+ expressed in units of 10ms. About 200-300 ms (value 20-30)
+ seems to be a good value.
+
+ Example: sccparam /dev/sc1 slot 20
+
+tail:
+ The time the transmitter will remain keyed after the last
+ byte of a packet has been transferred to the SCC. This is
+ necessary because the CRC and a flag still have to leave the
+ SCC before the transmitter is keyed down. The value depends
+ on the baudrate selected. A few character times should be
+ sufficient, e.g. 40ms at 1200 baud. (value 4)
+ The value of this parameter is in 10ms units.
+
+ Example: sccparam /dev/sc3 4
+
+full:
+ The full-duplex mode switch. This can be one of the folowing
+ values:
+
+ 0: The interface will operate in CSMA mode (the normal
+ half-duplex packet radio operation)
+ 1: Fullduplex mode, i.e. the transmitter will be keyed at
+ any time, without checking the received carrier. It
+ will be unkeyed when there are no packets to be sent.
+ 2: Like 1, but the transmitter will remain keyed, also
+ when there are no packets to be sent. Flags will be
+ sent in that case, until a timeout (parameter 10)
+ occurs.
+
+ Example: sccparam /dev/sc1 fulldup off
+
+wait:
+ The initial waittime before any transmit attempt, after the
+ frame has been queue for transmit. This is the length of
+ the first slot in CSMA mode. In fullduplex modes it is
+ set to 0 for maximum performance.
+ The value of this parameter is in 10ms units.
+
+ Example: sccparam /dev/sc2 wait 4
+
+maxkey:
+ The maximal time the transmitter will be keyed to send
+ packets, in seconds. This can be useful on busy CSMA
+ channels, to avoid "getting a bad reputation" when you are
+ generating a lot of traffic. After the specified time has
+ elapsed, no new frame will be started. Instead, the trans-
+ mitter will be switched off for a specified time (parameter
+ min), and then the selected algorithm for keyup will be
+ started again.
+ The value 0 as well as "off" will disable this feature,
+ and allow infinite transmission time.
+
+ Example: sccparam /dev/sc1 maxk 20
+
+min:
+ This is the time the transmitter will be switched off when
+ the maximum transmission time is exceeded.
+
+ Example: sccparam /dev/sc4 min 10
+
+idle
+ This parameter specifies the maximum idle time in fullduplex
+ 2 mode, in seconds. When no frames have been sent for this
+ time, the transmitter will be keyed down. A value of 0 is
+ has same result as the fullduplex mode 1. This parameter
+ can be disabled.
+
+ Example: sccparam /dev/sc3 idle off # transmit forever
+
+maxdefer
+ This is the maximum time (in seconds) to wait for a free channel
+ to send. When this timer expires the transmitter will be keyed
+ IMMEDIATLY. If you love to get trouble with other users you
+ should set this to a very low value ;-)
+
+ Example: sccparam /dev/sc1 maxdefer 240 # 2 minutes
+
+
+txoff:
+ When this parameter has the value 0, the transmission of packets
+ is enable. Otherwise it is disabled.
+
+ Example: sccparam /dev/sc3 txoff on
+
+group:
+ It is possible to build special radio equipment to use more than
+ one frequency on the same bad, e.g. using several receivers and
+ only one transmitter that can be switched between frequencies.
+ Also, you can connect several radios that are active on the same
+ band. In these cases, it is not possible, or not a good idea, to
+ transmit on more than one frequency. The SCC driver provides a
+ method to lock transmitters on different interfaces, using the
+ "param <interface> group <x>" command. This will only work when
+ you are using CSMA mode (parameter full = 0).
+ The number <x> must be 0 if you want no group restrictions, and
+ can be computed as follows to create restricted groups:
+ <x> is the sum of some OCTAL numbers:
+
+ 200 This transmitter will only be keyed when all other
+ transmitters in the group are off.
+ 100 This transmitter will only be keyed when the carrier
+ detect of all other interfaces in the group is off.
+ 0xx A byte that can be used to define different groups.
+ Interfaces are in the same group, when the logical AND
+ between their xx values is nonzero.
+
+ Examples:
+ When 2 interfaces use group 201, their transmitters will never be
+ keyed at the same time.
+ When 2 interfaces use group 101, the transmitters will only key
+ when both channels are clear at the same time. When group 301,
+ the transmitters will not be keyed at the same time.
+
+ Don't forget to convert the octal numbers into decimal before
+ you set the parameter.
+
+ Example: (to be written)
+
+softdcd:
+ use a software dcd instead of the real one... Useful for a very
+ slow squelch.
+
+ Example: sccparam /dev/sc1 soft on
+
+
+slip:
+ use slip encoding instead of kiss
+
+ Example: sccparam /dev/sc2 slip on
+
+
+
+2. Problems
+===========
+
+We are poking around in somebody else's code, so everything may change
+from one patchlevel to another... If the patches fail, try the
+following:
+
+2.1 /linux/drivers/char/Makefile
+================================
+
+Add "scc.o" to the definition of OBJS and "scc.c" to SRCS
+
+
+2.2 /linux/include/linux/tty_driver.h
+=====================================
+
+add the following DEFINE:
+
+#define TTY_DRIVER_TYPE_SCC 0x0005
+
+
+2.3 /linux/drivers/char/tty_io.c
+================================
+
+in tty_init() add the line
+
+ kmem_start=scc_init(kmem_start);
+
+just before "return kmem_start".
+
+2.4 /linux/arch/i386/config.in
+==============================
+
+somewhere in that file add:
+
+ comment 'Z8530 SCC driver for Amateur Packet Radio'
+ bool 'KISS emulator for Z8530 based HDLC cards' CONFIG_SCC y
+ comment ''
+
+
+
+2.5 Other problems
+==================
+
+If you have tx-problems with your BayCom USCC card please check
+the manufacturer of the 8530. SGS chips have a slightly
+different timing. Try Zilog... I have no information if this
+driver works with baudrates higher than 1200 baud. A solution is
+to write to register 8 instead to the data port, but this won't
+work with the ESCC chips *SIGH!*
+
+I got reports that the driver has problems on some 386-based systems.
+(i.e. Amstrad) Those systems have a bogus AT bus timing which will
+lead to delayed answers on interrupts. You can recognize these
+problems by looking at the output of Sccstat for the suspected
+port. See if it shows under- and overruns you own such a system.
+Perhaps it will help if you simplify the scc_isr() function a bit.
+You'll find a slightly faster version in the files scc_isr_intack
+or scc_isr_novec.
+
+
+Delayed processing of received data: This depends on
+
+- the kernel version
+
+- kernel profiling compiled or not
+
+- the rather slow receiver in tty_io.c
+
+- a high interrupt load
+
+- a high load of the maching --- running X, Xmorph, XV and Povray,
+ while compiling the kernel... hmm ... even with 32 MB RAM ... ;-)
+
+- NET's speed itself.
+
+
+Kernel panics (based on excerpts from /linux/README)
+
+
+- if a bug results in a message like
+
+ unable to handle kernel paging request at address C0000010
+ Oops: 0002
+ EIP: 0010:XXXXXXXX
+ eax: xxxxxxxx ebx: xxxxxxxx ecx: xxxxxxxx edx: xxxxxxxx
+ esi: xxxxxxxx edi: xxxxxxxx ebp: xxxxxxxx
+ ds: xxxx es: xxxx fs: xxxx gs: xxxx
+ Pid: xx, process nr: xx
+ xx xx xx xx xx xx xx xx xx xx
+
+ or similar kernel debugging information on your screen or in your
+ system log, please duplicate it *exactly*. The dump may look
+ incomprehensible to you, but it does contain information that may
+ help debugging the problem. The text above the dump is also
+ important: it tells something about why the kernel dumped code (in
+ the above example it's due to a bad kernel pointer)
+
+- in debugging dumps like the above, please look up what the EIP value
+ means. The hex value as such doesn't help me or anybody else very much:
+ it will depend on your particular kernel setup. What you should do is
+ take the hex value from the EIP line (ignore the "0010:"), and look it up
+ in the kernel namelist to see which kernel function contains the offending
+ address.
+
+ To find out the kernel function name, you'll need to
+
+ less /linux/System.map
+
+ This will give you a list of kernel addresses sorted in ascending
+ order, from which it is simple to find the function that contains the
+ offending address. Note that the address given by the kernel
+ debugging messages will not necessarily match exactly with the
+ function addresses (in fact, that is very unlikely), so you can't
+ just 'grep' the list: the list will, however, give you the starting
+ point of each kernel function, so by looking for the function that
+ has a starting address lower than the one you are searching for but
+ is followed by a function with a higher address you will find the one
+ you want. In fact, it may be [IS!] a good idea to include a bit of
+ "context" in your problem report, giving a few lines around the
+ interesting one.
+
+ I included a small program which does this for you. Just call
+
+ grep_eip /linux/System.map address
+
+ for example: grep_eip /linux/System.map 182f98
+
+- alternately, you can use gdb on a running kernel. (read-only; i.e. you
+ cannot change values or set break points.) To do this, first compile the
+ kernel with -g; edit arch/i386/Makefile appropriately, then do a "make
+ clean". You'll also need to enable CONFIG_PROC_FS (via "make config").
+
+ After you've rebooted with the new kernel, do "gdb vmlinux /proc/kcore".
+ You can now use all the usual gdb commands. The command to look up the
+ point where your system crashed is "l *0xXXXXXXXX". (Replace the XXXes
+ with the EIP value.)
+
+ gdb'ing a non-running kernel currently fails because gdb (wrongly)
+ disregards the starting offset for which the kernel is compiled.
+
+
+
+If you can't solve a problem, send me
+
+- a description of the problem,
+- information on your hardware (computer system, scc board, modem)
+- your kernel version
+- the output of sccstat /dev/sc# ("#" is the No. of the channel)
+- the settings of "speed", "clock" and "mode" for that channel
+ in /etc/z8530drv.rc
+- your scc_config.h
+
+
+And always remember:
+The 1.1.* kernel series is for alpha tests -- use at your own risk ;-)
+The 1.2.* series should run reliable. This driver perhaps NOT!
+The 1.3.* kernel series is for alpha tests again... you get the idea!

-
-0. Installation of the package
-==============================
-
-Run SCC-Install. If one (or more) of the patches fails PLEASE consult
-chapter 2 (and READ IT of course!)
-
-
-
-1. Initialization and attachment of the channels
-================================================
-
-To use the driver, 3 steps must be performed:
-
- 1. Global initialization of the driver in the kernel
- 2. Setup of parameters with sccinit
- 2. Attachment of each channel in the packet software
-
-The global initialization is needed to reset all SCCs and to
-install a common interrupt handler. Also, the hardware addresses
-of the chips are defined in this step. In the second step, each
-channel is set up for the intended use.
-
-
-
-1.1. Initialization
-===================
-
-Initialization of the hardware is performed by setting the defines and
-variables in the file "/linux/drivers/char/scc_config.h". You can change
-a number of parameters.

-After you changed a parameter you have to recompile a new kernel image file.
-
-The channel number ranges from 0 to (2 * Nchips) - 1,
-where Nchips is the number of chips.
-
-The crystal clock is specified as 4.9152 MHz. Other frequencies
-can be used, and this parameter should be adjusted accordingly.
-
-
-You can define your scc type with Board
-
- SCC type value
- ---------------------------------
- PA0HZP SCC card PA0HZP
- EAGLE card EAGLE
- PC100 card PC100
- PRIMUS-PC (DG9BL) card PRIMUS
- BayCom (U)SCC card BAYCOM
-
-
-NOTE:
-=====
-
-If you only know the parameters for the PE1CHL driver for DOS,
-run gencfg. It will generate the correct port addresses (I hope).
-Its parameters are exactly the same as the ones you use with
-the "attach scc" command in net, except that the string "init" must
-not appear. Example:
-
-gencfg 2 0x150 4 2 0 1 0x168 9 4915200
-
-will print a short form of scc_config.h for the OptoSCC to stdout.
-("short" <=> few comments).
-
-gencfg 2 0x300 2 4 5 -4 0 7 4915200 0x10
-
-does the same for the BayCom USCC card. I my opinion it is much easier
-to edit scc_config.h...
-
-
-1.2 initializing the driver on bootup
-=====================================
-
-
-To setup a number parameters you must run /sbin/sccinit from one
-of your rc.*-files. This has to be done BEFORE the start of
-NET or the ax25attach. Sccinit reads the file /etc/z8530drv.rc
-and sets the MODEM and KISS parameters. A sample file is
-delivered with this package. Change it to your needs:
-
-Each channel definition is divided into three sections. An
-example for /dev/sc1:
-
-# DEVICE
-
-device /dev/sc1 # the device for the following params
-
-# MODEM
-
-speed 1200 # the default baudrate
-clock dpll # clock source:
- # dpll = normal halfduplex operation
- # external = MODEM provides own Rx/Tx clock
- # divider = use fullduplex divider if
- # installed (1)
-mode nrzi # HDLC encoding mode
- # nrzi = 1k2 MODEM, G3RUH 9k6 MODEM
- # nrz = DF9IC 9k6 MODEM
-# KISS (Layer 1)
-
-txdelay 36 # (see chapter 1.4)
-persist 64
-slot 8
-tail 8
-fulldup 0
-wait 12
-min 3
-maxkey 7
-idle 3
-maxdef 120
-group 0
-txoff off
-softdcd on
-slip off
-
-The order WITHIN these sections is unimportant. The order OF these
-sections IS important. The MODEM parameters are set with the first
-recognized KISS paramer...
-
-Please note that you can initialize the board only once after boot.
-You can change all paramters but "mode" and "clock" later with the
-Sccparam program or through KISS. Just to avoid securety holes...
-
-(1) this divider is usually mounted on the SCC-PBC (PA0HZP) or not
- present at all (BayCom). It feeds back the output of the DPLL
- (digital pll) as transmit clock. Using this mode without a divider
- installed will normally result in keying the transceiver until
- maxkey expires --- of course without sending anything (useful).
-
-
-1.3. Attach commands
-====================
-
-When the linux has startup, the SCC driver has been initialized,
-you can attach the channels in your packet software. This is done
-by open the scc devices by using the attach asy command.
-The SCC-drivers emulates the scc devices as serial asy ports,
-this means e.g. that the baudrate can be set in the attach command.
-
-
-Example Wampes:
-
-#############################################################################################
-# Wampes device attach
-# NOTE: Interfacename and the device must be the same!!
-# Usage: attach asy 0 0 slip|vjslip|ax25ui|ax25i|nrs|kissui <label> 0 <mtu> <speed> [ip_addr]
-#
-attach asy 0 0 kissi sc1 256 256 1200 # Attach SCC channel 1 in 1200 baud
-attach asy 0 0 kissi sc2 256 256 1200 # Attach SCC channel 2 in 1200 baud
-attach asy 0 0 kissui sc3 256 256 38400 # Attach SCC channel 3 in 38400 baud
-attach asy 0 0 kissui sc4 256 256 9600 # Attach SCC channel 4 in 9600 baud
-# ^
-# for WAMPES 921229 use here: ax25
-#
-
-Example JNOS:
-
-############################################
-# JNOS device attach
-#
-#attach asy sc1 0 ax25 sc1 256 256 1200
-#attach asy sc2 0 ax25 sc2 256 256 1200
-#attach asy sc3 0 ax25 sc3 256 256 300
-#attach asy sc4 0 ax25 sc4 256 256 4800
-#
-#
-
-
-It allows AX.25 communication without a TNC. Only a MODEM is
-needed. The parameters have the same meaning as in KISS mode.
-In fact, the AX.25 mode is emulating an extended KISS TNC, so
-the same commands can be used to set the parameters of the
-interface (see below).
-
-To be able to run fullduplex using an SCC in AX.25 mode, an
-external divider must be available, that divides the baudrate
-generator clock available on the TRxC pin by 32, and puts the
-resulting signal on the RTxC pint of the same channel of the SCC.
-Such a divider is not necessary for normal CSMA packet radio
-operation, but interrupt overhead is slightly reduced if you
-still install it.
-
-
-
-1.4. Displaying SCC Parameters:
-===============================
-
-Once a SCC channel has been attached, the parameter settings and
-some statistic information can be shown using the param program:
-
-dl1bke-u:~$ sccstat /dev/sc1
-
-Parameters:
-
-speed : 1200 baud
-txdelay : 36
-persist : 255
-slottime : 0
-txtail : 8
-fulldup : 1
-waittime : 12
-mintime : 3 sec
-maxkeyup : 7 sec
-idletime : 3 sec
-maxdefer : 120 sec
-group : 0x00
-txoff : off
-softdcd : on
-SLIP : off
-
-Status:
-
-HDLC Z8530 Interrupts Queues
------------------------------------------------------------------------
-Sent : 273 RxOver : 0 RxInts : 125074 RxQueue : 0
-Received : 1095 TxUnder: 0 TxInts : 4684 TxQueue : 0
-RxErrors : 1591 ExInts : 11776
-KissErrors : 0 SpInts : 1503 NoSpace : 0
-Tx State : idle
-
-Memory allocated:
-
-Total : 1
-RxAlloc: 0
-TxAlloc: 1
-
-
-The status info shown is:
-
-Sent - number of frames transmitted
-Received - number of frames received
-RxErrors - number of receive errors (CRC, ABORT)
-KissErrors - number of KISS errors (should be zero...)
-Tx State - status of the Tx interrupt handler: idle/busy/active/tail (2)
-RxOver - number of receiver overruns
-TxUnder - number of transmitter underruns
-RxInts - number of receiver interrupts
-TxInts - number of transmitter interrupts
-EpInts - number of receiver special condition interrupts
-SpInts - number of external/status interrupts
-RxQueue - number of received packets enqueued for this channel
-TxQueue - number of packets enqueued for Tx
-NoSpace - number of times the receiver buffer pool was found empty
-
-
-An overrun is abnormal. If lots of these occur, the product of
-baudrate and number of interfaces is too high for the processing
-power of you computer. If "Space" errors occur, specify a higher
-number of buffers in the "scc.h" file.
-
-
-1.5 Setting Parameters
-======================
-
-
-The setting of parameters of the emulated KISS TNC is done in the
-same way in the SCC driver. You can change parameters by using
-the command param in NET or NOS
-
- param <iface> <paramname> <value>
-
-or use the program "sccparam":
-
- sccparam <device> <paramname> <decimal-|hexadecimal value>
-
-You can change the following parameters:
-
-param : value
-------------------------
-speed : 1200
-txdelay : 36
-persist : 255
-slottime : 0
-txtail : 8
-fulldup : 1
-waittime : 12
-mintime : 3
-maxkeyup : 7
-idletime : 3
-maxdefer : 120
-group : 0x00
-txoff : off
-softdcd : on
-SLIP : off
-
-
-The parameters have the following meaning:
-
-speed:
- The baudrate on this channel in bits/sec
-
- Example: sccparam /dev/sc4 speed 9600
-
-txdelay:
- The delay (in units of 10ms) after keying of the
- transmitter, until the first byte is sent. This is usually
- called "TXDELAY" in a TNC. When 0 is specified, the driver
- will just wait until the CTS signal is asserted. This
- assumes the presence of a timer or other circuitry in the
- MODEM and/or transmitter, that asserts CTS when the
- transmitter is ready for data.
- A normal value of this parameter is 30-36.
-
- Example: sccparam /dev/sc1 txd 20
-
-persist:
- This is the probability that the transmitter will be keyed
- when the channel is found to be free. It is a value from 0
- to 255, and the probability is (value+1)/256. The value
- should be somewhere near 50-60, and should be lowered when
- the channel is used more heavily.
-
- Example: sccparam /dev/sc3 persist 20
-
-slottime:
- This is the time between samples of the channel. It is
- expressed in units of 10ms. About 200-300 ms (value 20-30)
- seems to be a good value.
-
- Example: sccparam /dev/sc1 slot 20
-
-tail:
- The time the transmitter will remain keyed after the last
- byte of a packet has been transferred to the SCC. This is
- necessary because the CRC and a flag still have to leave the
- SCC before the transmitter is keyed down. The value depends
- on the baudrate selected. A few character times should be
- sufficient, e.g. 40ms at 1200 baud. (value 4)
- The value of this parameter is in 10ms units.
-
- Example: sccparam /dev/sc3 4
-
-full:
- The full-duplex mode switch. This can be one of the folowing
- values:
-
- 0: The interface will operate in CSMA mode (the normal
- half-duplex packet radio operation)
- 1: Fullduplex mode, i.e. the transmitter will be keyed at
- any time, without checking the received carrier. It
- will be unkeyed when there are no packets to be sent.
- 2: Like 1, but the transmitter will remain keyed, also
- when there are no packets to be sent. Flags will be
- sent in that case, until a timeout (parameter 10)
- occurs.
-
- Example: sccparam /dev/sc1 fulldup off
-
-wait:
- The initial waittime before any transmit attempt, after the
- frame has been queue for transmit. This is the length of
- the first slot in CSMA mode. In fullduplex modes it is
- set to 0 for maximum performance.
- The value of this parameter is in 10ms units.
-
- Example: sccparam /dev/sc2 wait 4
-
-maxkey:
- The maximal time the transmitter will be keyed to send
- packets, in seconds. This can be useful on busy CSMA
- channels, to avoid "getting a bad reputation" when you are
- generating a lot of traffic. After the specified time has
- elapsed, no new frame will be started. Instead, the trans-
- mitter will be switched off for a specified time (parameter
- min), and then the selected algorithm for keyup will be
- started again.
- The value 0 as well as "off" will disable this feature,
- and allow infinite transmission time.
-
- Example: sccparam /dev/sc1 maxk 20
-
-min:
- This is the time the transmitter will be switched off when
- the maximum transmission time is exceeded.
-
- Example: sccparam /dev/sc4 min 10
-
-idle
- This parameter specifies the maximum idle time in fullduplex
- 2 mode, in seconds. When no frames have been sent for this
- time, the transmitter will be keyed down. A value of 0 is
- has same result as the fullduplex mode 1. This parameter
- can be disabled.
-
- Example: sccparam /dev/sc3 idle off # transmit forever
-
-maxdefer
- This is the maximum time (in seconds) to wait for a free channel
- to send. When this timer expires the transmitter will be keyed
- IMMEDIATLY. If you love to get trouble with other users you
- should set this to a very low value ;-)
-
- Example: sccparam /dev/sc1 maxdefer 240 # 2 minutes
-
-
-txoff:
- When this parameter has the value 0, the transmission of packets
- is enable. Otherwise it is disabled.
-
- Example: sccparam /dev/sc3 txoff on
-
-group:
- It is possible to build special radio equipment to use more than
- one frequency on the same bad, e.g. using several receivers and
- only one transmitter that can be switched between frequencies.
- Also, you can connect several radios that are active on the same
- band. In these cases, it is not possible, or not a good idea, to
- transmit on more than one frequency. The SCC driver provides a
- method to lock transmitters on different interfaces, using the
- "param <interface> group <x>" command. This will only work when
- you are using CSMA mode (parameter full = 0).
- The number <x> must be 0 if you want no group restrictions, and
- can be computed as follows to create restricted groups:
- <x> is the sum of some OCTAL numbers:
-
- 200 This transmitter will only be keyed when all other
- transmitters in the group are off.
- 100 This transmitter will only be keyed when the carrier
- detect of all other interfaces in the group is off.
- 0xx A byte that can be used to define different groups.
- Interfaces are in the same group, when the logical AND
- between their xx values is nonzero.
-
- Examples:
- When 2 interfaces use group 201, their transmitters will never be
- keyed at the same time.
- When 2 interfaces use group 101, the transmitters will only key
- when both channels are clear at the same time. When group 301,
- the transmitters will not be keyed at the same time.
-
- Don't forget to convert the octal numbers into decimal before
- you set the parameter.
-
- Example: (to be written)
-
-softdcd:
- use a software dcd instead of the real one... Useful for a very
- slow squelch.
-
- Example: sccparam /dev/sc1 soft on
-
-
-slip:
- use slip encoding instead of kiss
-
- Example: sccparam /dev/sc2 slip on
-
-
-
-2. Problems
-===========
-
-We are poking around in somebody else's code, so everything may change
-from one patchlevel to another... If the patches fail, try the
-following:
-
-2.1 /linux/drivers/char/Makefile
-================================
-
-Add "scc.o" to the definition of OBJS and "scc.c" to SRCS
-
-
-2.2 /linux/include/linux/tty_driver.h
-=====================================
-
-add the following DEFINE:
-
-#define TTY_DRIVER_TYPE_SCC 0x0005
-
-
-2.3 /linux/drivers/char/tty_io.c
-================================
-
-in tty_init() add the line
-
- kmem_start=scc_init(kmem_start);
-
-just before "return kmem_start".
-
-2.4 /linux/arch/i386/config.in
-==============================
-
-somewhere in that file add:
-
- comment 'Z8530 SCC driver for Amateur Packet Radio'
- bool 'KISS emulator for Z8530 based HDLC cards' CONFIG_SCC y
- comment ''
-
-
-
-2.5 Other problems
-==================
-
-If you have tx-problems with your BayCom USCC card please check
-the manufacturer of the 8530. SGS chips have a slightly
-different timing. Try Zilog... I have no information if this
-driver works with baudrates higher than 1200 baud. A solution is
-to write to register 8 instead to the data port, but this won't
-work with the ESCC chips *SIGH!*
-
-I got reports that the driver has problems on some 386-based systems.
-(i.e. Amstrad) Those systems have a bogus AT bus timing which will
-lead to delayed answers on interrupts. You can recognize these
-problems by looking at the output of Sccstat for the suspected
-port. See if it shows under- and overruns you own such a system.
-Perhaps it will help if you simplify the scc_isr() function a bit.
-You'll find a slightly faster version in the files scc_isr_intack
-or scc_isr_novec.
-
-
-Delayed processing of received data: This depends on
-
-- the kernel version
-
-- kernel profiling compiled or not
-
-- the rather slow receiver in tty_io.c
-
-- a high interrupt load
-
-- a high load of the maching --- running X, Xmorph, XV and Povray,
- while compiling the kernel... hmm ... even with 32 MB RAM ... ;-)
-
-- NET's speed itself.
-
-
-Kernel panics (based on excerpts from /linux/README)
-
-
-- if a bug results in a message like
-
- unable to handle kernel paging request at address C0000010
- Oops: 0002
- EIP: 0010:XXXXXXXX
- eax: xxxxxxxx ebx: xxxxxxxx ecx: xxxxxxxx edx: xxxxxxxx
- esi: xxxxxxxx edi: xxxxxxxx ebp: xxxxxxxx
- ds: xxxx es: xxxx fs: xxxx gs: xxxx
- Pid: xx, process nr: xx
- xx xx xx xx xx xx xx xx xx xx
-
- or similar kernel debugging information on your screen or in your
- system log, please duplicate it *exactly*. The dump may look
- incomprehensible to you, but it does contain information that may
- help debugging the problem. The text above the dump is also
- important: it tells something about why the kernel dumped code (in
- the above example it's due to a bad kernel pointer)
-
-- in debugging dumps like the above, please look up what the EIP value
- means. The hex value as such doesn't help me or anybody else very much:
- it will depend on your particular kernel setup. What you should do is
- take the hex value from the EIP line (ignore the "0010:"), and look it up
- in the kernel namelist to see which kernel function contains the offending
- address.
-
- To find out the kernel function name, you'll need to
-
- less /linux/System.map
-
- This will give you a list of kernel addresses sorted in ascending
- order, from which it is simple to find the function that contains the
- offending address. Note that the address given by the kernel
- debugging messages will not necessarily match exactly with the
- function addresses (in fact, that is very unlikely), so you can't
- just 'grep' the list: the list will, however, give you the starting
- point of each kernel function, so by looking for the function that
- has a starting address lower than the one you are searching for but
- is followed by a function with a higher address you will find the one
- you want. In fact, it may be [IS!] a good idea to include a bit of
- "context" in your problem report, giving a few lines around the
- interesting one.
-
- I included a small program which does this for you. Just call
-
- grep_eip /linux/System.map address
-
- for example: grep_eip /linux/System.map 182f98
-
-- alternately, you can use gdb on a running kernel. (read-only; i.e. you
- cannot change values or set break points.) To do this, first compile the
- kernel with -g; edit arch/i386/Makefile appropriately, then do a "make
- clean". You'll also need to enable CONFIG_PROC_FS (via "make config").
-
- After you've rebooted with the new kernel, do "gdb vmlinux /proc/kcore".
- You can now use all the usual gdb commands. The command to look up the
- point where your system crashed is "l *0xXXXXXXXX". (Replace the XXXes
- with the EIP value.)
-
- gdb'ing a non-running kernel currently fails because gdb (wrongly)
- disregards the starting offset for which the kernel is compiled.
-
-
-
-If you can't solve a problem, send me
-
-- a description of the problem,
-- information on your hardware (computer system, scc board, modem)
-- your kernel version
-- the output of sccstat /dev/sc# ("#" is the No. of the channel)
-- the settings of "speed", "clock" and "mode" for that channel
- in /etc/z8530drv.rc
-- your scc_config.h
-
-
-And always remember:
-The 1.1.* kernel series is for alpha tests -- use at your own risk ;-)
-The 1.2.* series should run reliable. This driver perhaps NOT!
-The 1.3.* kernel series is for alpha tests again... you get the idea!

**********************
-
- v1.93 ALPHA (95/08/10)
- - Should work with both 1.2.x and 1.3.x now. (I hope)
- - Renamed arc0w ("Windows" protocol) to arc0e ("Ethernet-Encap")
- because the protocol used isn't necessarily limited to
- Microsoft.
-
- v1.92 ALPHA (95/07/11)
- - Fixes to make things work with kernel 1.3.x. Completely broke
- 1.2.x support. Oops? 1.2.x users keep using 1.91 ALPHA until I
- get out a version that supports both.
-
- v1.91 ALPHA (95/07/02)
- - Oops. Exception packets hit us again! I remembered to test
- them in ethernet-protocol mode, but due to the many various
- changes they broke in RFC1201 instead. All fixed.
- - A long-standing bug with "exception" packets not setting
- protocol_id properly has been corrected. This would have caused
- random problems talking to non-Linux servers. I've also sent in
- a patch to fix this in the latest stable ARCnet (now 1.02).
- - ARC_P_IPX is an RFC1201 protocol too. Thanks, Tomasz.
- - We're now "properly" (I think) handling the multiple 'tbusy' and
- 'start' flags (one for each protocol device) better.
- - The driver should now start without a NULL-pointer dereference
- if you aren't connected to the network.
+
+ v2.00 (95/09/06)
+ - THIS IS ONLY A SUMMARY. The complete changelog is available
+ from me upon request.
+
+ - ARCnet RECON messages are now detected and logged. These occur
+ when a new computer is powered up on the network, or in a
+ constant stream when the network cable is broken. Thanks to
+ Tomasz Motylewski for this. You must have D_EXTRA enabled
+ if you want these messages sent to syslog, otherwise they will
+ only show up in the network statistics (/proc/net/dev).
+ - The TX Acknowledge flag is now checked, and a log message is sent
+ if a completed transmit is not ACK'd. (I have yet to have this
+ happen to me.)
+ - Debug levels are now completely different. See the README.
+ - Many code cleanups, with several no-longer-necessary and some
+ completely useless options removed.
+ - Multiprotocol support. You can now use the "arc0e" device to
+ send "Ethernet-Encapsulation" packets, which are compatible with
+ Windows for Workgroups and LAN Manager, and possibly other
+ software. See the README for more information.
+ - Documentation updates and improvements.
- v1.90 ALPHA (95/06/18)
- - Removal of some outdated and messy config options (no one has
- ever complained about the defaults since they were introduced):
- DANGER_PROBE, EXTRA_DELAYS, IRQ_XMIT, CAREFUL_XMIT,
- STRICT_MEM_DETECT, LIMIT_MTU, USE_TIMER_HANDLER. Also took out
- a few "#if 0" sections which are no longer useful.
- - Cleaned up debug levels - now instead of levels, there are
- individual flags. Watch out when changing with ifconfig.
- - More cleanups and beautification. Removed more dead code and
- made sure every function was commented.
- - Fixed the DETECT_RECONFIGS option so that it actually _won't_
- detect reconfigs. Previously, the RECON irq would be disabled
- but the recon messages would still be logged on the next normal
- IRQ.
- - Initial support for "multiprotocol" ARCnet (this involved a LOT
- of reorganizing!). Added an arc0w device, which allows us to
- talk to ethernet-over-ARCnet TCP/IP protocol. To use it, ifconfig
- arc0 and arc0w (in that order). For now, ethernet-protocol
- hosts should have routes through arc0w - eventually I hope to
- make things more automatic.
- v1.11 ALPHA (95/06/07)
- - Tomasz saves the day again with patches to fix operation if the
- new VERIFY_ACK option is disabled.
- - LOTS of little code cleanups/improvements by Tomasz.
- - Changed autoprobe, since the "never-changing command port"
- probe was causing problems for some people. I also reset the
- card fewer times during the probe if DANGER_PROBE is defined,
- since DANGER_PROBE seems to be a more reliable method anyway.
- - It looks like the null-pointer problem was finally REALLY fixed
- by some change from Linux 1.2.8 to 1.2.9. How handy!
- v1.10 ALPHA (95/04/15)
- - Fixed (?) some null-pointer dereference bugs
- - Added better network error detection (from Tomasz) - in
- particular, we now notice when our network isn't connected,
- also known as a "network reconfiguration."
- - We now increment lp->stats.tx_dropped in several more places,
- on a suggestion from Tomasz.
- - Minor cleanups/spelling fixes.
- - We now monitor the TXACK bit in the status register: we don't do
- anything with it yet, just notice when a transmitted packet isn't
- acknowledged.
- - Minor fix with sequence numbers (sometimes they were being sent in
- the wrong order due to Linux's packet queuing).
+ v1.02 (95/06/21)
+ - A fix to make "exception" packets sent from Linux receivable
+ on other systems. (The protocol_id byte was sometimes being set
+ incorrectly, and Linux wasn't checking it on receive so it
+ didn't show up)
+
v1.01 (95/03/24)
- Fixed some IPX-related bugs. (Thanks to Tomasz Motylewski
<motyl@tichy.ch.uj.edu.pl> for the patches to make arcnet work
with dosemu!)
+
v1.00 (95/02/15)
- Initial non-alpha release.
TO DO:
- Test in systems with NON-ARCnet network cards, just to see if
- autoprobe kills anything. Currently, we do cause some NE2000's to
- die.
+ autoprobe kills anything. Currently, we do cause some NE2000's
+ to die. Autoprobe is also way too slow and verbose, particularly
+ if there ARE no ARCnet cards.
- What about cards with shared memory that can be "turned off?"
- NFS mount freezes after several megabytes to SOSS for DOS.
unmount/remount fixes it. Is this arcnet-specific? I don't know.
- Add support for "old" (RFC1051) protocol arcnet, such as AmiTCP
and NetBSD. Work in Tomasz' initial support for this.
- - How about TCP/IP over netbios?
+ - How about TCP/IP over netbios? Or vice versa?
- Some newer ARCnets support promiscuous mode, supposedly.
If someone sends me information, I'll try to implement it.
- Remove excess lock variables that are probably not necessary
