- Text File for 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
- UP BROADCAST RUNNING NOARP MULTICAST MTU:600 Metric:1
- RX packets:0 errors:0 dropped:0 overruns:0 frame:0
- TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 coll: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"
