* Does anybody know if Boca 16 ports card would work with freebsd 2.0.5 ? and
* can you use two of them? instad of terminal server, please include a hint
* how to configuer the server and the modems with them


This should be documented somewhere...


This is how I have one 16-port boca board configured.  Works
fine.   Unfortunantly the sio driver doesn't take advantage
of the boca's interrupt register and so it polls all 16 ports
every time any of the interrupts.

I tried to fix the driver, but it kept hanging.  The NetBSD
driver does the right thing (I wrote the first version), but 
that doesn't help much.

I don't know if you can run two of them on the same FreeBSD 
system.  Because of the driver problem, I'm figuring that if
I want that many serial ports I'll dedicate a machine to being
a terminal server and run NetBSD on it.   In every other respect,
I find FreeBSD easier to deal with.  (Or I did when I ran 2.0.  
2.0.5 crashes way too often)
