The COPS LocalTalk Linux driver (cops.c) |
|
======================================== |
|
|
|
By Jay Schulist <[email protected]> |
|
|
|
This driver has two modes and they are: Dayna mode and Tangent mode. |
|
Each mode corresponds with the type of card. It has been found |
|
that there are 2 main types of cards and all other cards are |
|
the same and just have different names or only have minor differences |
|
such as more IO ports. As this driver is tested it will |
|
become more clear exactly what cards are supported. |
|
|
|
Right now these cards are known to work with the COPS driver. The |
|
LT-200 cards work in a somewhat more limited capacity than the |
|
DL200 cards, which work very well and are in use by many people. |
|
|
|
TANGENT driver mode: |
|
- Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200 |
|
|
|
DAYNA driver mode: |
|
- Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95, |
|
- Farallon PhoneNET PC III, Farallon PhoneNET PC II |
|
|
|
Other cards possibly supported mode unknown though: |
|
- Dayna DL2000 (Full length) |
|
|
|
The COPS driver defaults to using Dayna mode. To change the driver's |
|
mode if you built a driver with dual support use board_type=1 or |
|
board_type=2 for Dayna or Tangent with insmod. |
|
|
|
Operation/loading of the driver |
|
=============================== |
|
|
|
Use modprobe like this: /sbin/modprobe cops.o (IO #) (IRQ #) |
|
If you do not specify any options the driver will try and use the IO = 0x240, |
|
IRQ = 5. As of right now I would only use IRQ 5 for the card, if autoprobing. |
|
|
|
To load multiple COPS driver Localtalk cards you can do one of the following:: |
|
|
|
insmod cops io=0x240 irq=5 |
|
insmod -o cops2 cops io=0x260 irq=3 |
|
|
|
Or in lilo.conf put something like this:: |
|
|
|
append="ether=5,0x240,lt0 ether=3,0x260,lt1" |
|
|
|
Then bring up the interface with ifconfig. It will look something like this:: |
|
|
|
lt0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-F7-00-00-00-00-00-00-00-00 |
|
inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 |

|

|
Netatalk Configuration |
|
====================== |
|
|
|
You will need to configure atalkd with something like the following to make |
|
it work with the cops.c driver. |
|
|
|
* For single LTalk card use:: |
|
|
|
dummy -seed -phase 2 -net 2000 -addr 2000.10 -zone "1033" |
|
lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033" |
|
|
|
* For multiple cards, Ethernet and LocalTalk:: |
|
|
|
eth0 -seed -phase 2 -net 3000 -addr 3000.20 -zone "1033" |
|
lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033" |
|
|
|
* For multiple LocalTalk cards, and an Ethernet card. |
|
|
|
* Order seems to matter here, Ethernet last:: |
|
|
|
lt0 -seed -phase 1 -net 1000 -addr 1000.10 -zone "LocalTalk1" |
|
lt1 -seed -phase 1 -net 2000 -addr 2000.20 -zone "LocalTalk2" |
|
eth0 -seed -phase 2 -net 3000 -addr 3000.30 -zone "EtherTalk"
