The COPS LocalTalk Linux driver (cops.c)
|
||
|
========================================
|
||
|
|
||
|
By Jay Schulist <jschlst@samba.org>
|
||
|
|
||
|
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"
