Awhile back - (long) I wrote an IBM Token Ring device
driver capable of working with ANY IBM token ring card
MCA or otherwise (if Linux was going to work on MCA...)
The IBM Token Ring Technical Reference Manual is a frustrating nightmare
as an information source. Most of the information is there. And for any of
you who've written a driver, you know that most doesn't cut it. Here's what you're
up against if you try this:
Cards WILL return undocumented values.
The manual gives you the ports to poke at, but doesn't tell you what has to be set
The drivers I wrote link into the kernel (99.14 I think?). Ifconfig tok0 188.8.131.52
etc.. works.. you can ifconfg tok0 down/up, etc.
ring. Perhaps you can get further than I. Maybe I quit to early but didn't have the
time to hack away endlessly. If you get it working, I'd be glad to help out through
the end of the project.
If you want my code, post or mail and I'll clean it up to 1.1.18 - if things haven't
changed too much (cringe).
If I haven't responded in 1 day mail again as my silly pop reader (perl-pop1.0) started
tacking all incoming messages onto one big file lately. Strange.
