| 1 | Text File for the COPS LocalTalk Linux driver (cops.c). | ||
| 2 | By Jay Schulist <jschlst@samba.org> | ||
| 3 | |||
| 4 | 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 | inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 | ||
| 43 | UP BROADCAST RUNNING NOARP MULTICAST MTU:600 Metric:1 | ||
| 44 | RX packets:0 errors:0 dropped:0 overruns:0 frame:0 | ||
| 45 | TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 coll:0 | ||
| 46 | |||
| 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. | ||
| 61 | lt0 -seed -phase 1 -net 1000 -addr 1000.10 -zone "LocalTalk1" | ||
| 62 | lt1 -seed -phase 1 -net 2000 -addr 2000.20 -zone "LocalTalk2" | ||
| 63 | eth0 -seed -phase 2 -net 3000 -addr 3000.30 -zone "EtherTalk" | ||
