This driver has two modes and they are: Dayna mode and Tangent mode.
|
| 5 |
|
|
Each mode corresponds with the type of card. It has been found
|
| 6 |
|
|
that there are 2 main types of cards and all other cards are
|
| 7 |
|
|
the same and just have different names or only have minor differences
|
| 8 |
|
|
such as more IO ports. As this driver is tested it will
|
| 9 |
|
|
become more clear exactly what cards are supported.
|
| 10 |
|
|
|
| 11 |
|
|
Right now these cards are known to work with the COPS driver. The
|
| 12 |
|
|
LT-200 cards work in a somewhat more limited capacity than the
|
| 13 |
|
|
DL200 cards, which work very well and are in use by many people.
|
| 14 |
|
|
|
| 15 |
|
|
TANGENT driver mode:
|
| 16 |
|
|
Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200
|
| 17 |
|
|
DAYNA driver mode:
|
| 18 |
|
|
Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95,
|
| 19 |
|
|
Farallon PhoneNET PC III, Farallon PhoneNET PC II
|
| 20 |
|
|
Other cards possibly supported mode unknown though:
|
| 21 |
|
|
Dayna DL2000 (Full length)
|
| 22 |
|
|
|
| 23 |
|
|
The COPS driver defaults to using Dayna mode. To change the driver's
|
| 24 |
|
|
mode if you built a driver with dual support use board_type=1 or
|
| 25 |
|
|
board_type=2 for Dayna or Tangent with insmod.
|
| 26 |
|
|
|
| 27 |
|
|
** Operation/loading of the driver.
|
| 28 |
|
|
Use modprobe like this: /sbin/modprobe cops.o (IO #) (IRQ #)
|
| 29 |
|
|
If you do not specify any options the driver will try and use the IO = 0x240,
|
| 30 |
|
|
IRQ = 5. As of right now I would only use IRQ 5 for the card, if autoprobing.
|
| 31 |
|
|
|
| 32 |
|
|
To load multiple COPS driver Localtalk cards you can do one of the following.
|
| 33 |
|
|
|
| 34 |
|
|
insmod cops io=0x240 irq=5
|
| 35 |
|
|
insmod -o cops2 cops io=0x260 irq=3
|
| 36 |
|
|
|
| 37 |
|
|
Or in lilo.conf put something like this:
|
| 38 |
|
|
append="ether=5,0x240,lt0 ether=3,0x260,lt1"
|
| 39 |
|
|
|
| 40 |
|
|
Then bring up the interface with ifconfig. It will look something like this:
|
| 41 |
|
|
lt0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-F7-00-00-00-00-00-00-00-00
|
| 42 |
|
|

|

|
|
|
| 47 |
|
|
** Netatalk Configuration
|
| 48 |
|
|
You will need to configure atalkd with something like the following to make
|
| 49 |
|
|
it work with the cops.c driver.
|
| 50 |
|
|
|
| 51 |
|
|
* For single LTalk card use.
|
| 52 |
|
|
dummy -seed -phase 2 -net 2000 -addr 2000.10 -zone "1033"
|
| 53 |
|
|
lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
|
| 54 |
|
|
|
| 55 |
|
|
* For multiple cards, Ethernet and LocalTalk.
|
| 56 |
|
|
eth0 -seed -phase 2 -net 3000 -addr 3000.20 -zone "1033"
|
| 57 |
|
|
lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
|
| 58 |
|
|
|
| 59 |
|
|
* For multiple LocalTalk cards, and an Ethernet card.
|
| 60 |
|
|
* Order seems to matter here, Ethernet last.
