Okay, cool.  I had that explained to me once already, but I didn't
quite get it.

Okay.  I have the modem working now.  I've figured out that part of
what I was doing wrong was using cu to try to talk to the modem.  :)

But, while it works just fine as com2, it still doesn't work in
ISAPnP.  Shouldn't it get allocated an unused IRQ by NetBSD?  In PnP
mode, it gets assigned IRQ 4, which is already taken by com0.

Basically, I'm happy with the device now -- I know that I can get it
to work.  But I wouldn't mind figuring out how to get it to work in
PnP mode, just on general principles.  Anybody interested in helping?

Chris
