0004 The COPS LocalTalk Linux driver (cops.c)
0005 ========================================
0006
0007 By Jay Schulist <jschlst@samba.org>
0008
0009 This driver has two modes and they are: Dayna mode and Tangent mode.
0010 Each mode corresponds with the type of card. It has been found
0011 that there are 2 main types of cards and all other cards are
0012 the same and just have different names or only have minor differences
0013 such as more IO ports. As this driver is tested it will
0014 become more clear exactly what cards are supported.
0015
0016 Right now these cards are known to work with the COPS driver. The
0017 LT-200 cards work in a somewhat more limited capacity than the
0018 DL200 cards, which work very well and are in use by many people.
0019
0020 TANGENT driver mode:
0021 - Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200
0022
0023 DAYNA driver mode:
0024 - Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95,
0025 - Farallon PhoneNET PC III, Farallon PhoneNET PC II
0026
0027 Other cards possibly supported mode unknown though:
0028 - Dayna DL2000 (Full length)
0029
0030 The COPS driver defaults to using Dayna mode. To change the driver's
0031 mode if you built a driver with dual support use board_type=1 or
0032 board_type=2 for Dayna or Tangent with insmod.
0033
0034 Operation/loading of the driver
0035 ===============================
0036
0037 Use modprobe like this: /sbin/modprobe cops.o (IO #) (IRQ #)
0038 If you do not specify any options the driver will try and use the IO = 0x240,
0039 IRQ = 5. As of right now I would only use IRQ 5 for the card, if autoprobing.
0040
0041 To load multiple COPS driver Localtalk cards you can do one of the following::
0042
0043 insmod cops io=0x240 irq=5
0044 insmod -o cops2 cops io=0x260 irq=3
0045
0046 Or in lilo.conf put something like this::
0047
0048 append="ether=5,0x240,lt0 ether=3,0x260,lt1"
0049
0050 Then bring up the interface with ifconfig. It will look something like this::
0051
0052 lt0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-F7-00-00-00-00-00-00-00-00
0053 inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0

0056 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 coll:0
0057
0058 Netatalk Configuration
0059 ======================
0060
0061 You will need to configure atalkd with something like the following to make
0062 it work with the cops.c driver.
0063
0064 * For single LTalk card use::
0065
0066 dummy -seed -phase 2 -net 2000 -addr 2000.10 -zone "1033"
0067 lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
0068
0069 * For multiple cards, Ethernet and LocalTalk::
0070
0071 eth0 -seed -phase 2 -net 3000 -addr 3000.20 -zone "1033"
0072 lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
0073
0074 * For multiple LocalTalk cards, and an Ethernet card.
0075
0076 * Order seems to matter here, Ethernet last::
0077
0078 lt0 -seed -phase 1 -net 1000 -addr 1000.10 -zone "LocalTalk1"
0079 lt1 -seed -phase 1 -net 2000 -addr 2000.20 -zone "LocalTalk2"
0080 eth0 -seed -phase 2 -net 3000 -addr 3000.30 -zone "EtherTalk"
