| 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" |
