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"
