I do not have a Telebit so I cannot be sure, and you do not describe the exact
symptoms of your problem, but it sounds like the same thing I saw when first
setting things up. What would happen was that every time the phone would ring
the modem would cycle DTR and spawn a new getty. Is this what is happening??
At first I got around the problem by running my modems on the BellTech ICC
card, but some kind soul (yes, Greg I saw your message, tested it, and it
worked!!) told me to RTFM on asy(7) in the operating system guide. It turns
out there is a modem control entry point into the asy driver. Of course, ISC
does not create a special device file for the entry point, /dev/tty00 is
major 3 minor 0. But let us not flame :-}, what you want is a /dev entry with
major 3 minor 16 and then run your getty on that, or equivalently for tty01
make it major 3 minor 17. Although I am not using these ( the ICC driver works
fine thank you :-}), I did test the COM1 device and low-and-behold :-} it
answered the line just as you might expect!! Oh well, half the fun of running
ISC is figuring out these little foibles :-}!?!
