Hi guys! I'm a having a problem with my Supra Fax/Modem talking (or rather,
not talking) with mgetty.
What happens is after I start my system everything is honkydory until someone
dials in. Then, after they've logged out the Supra refuses to talk to the
Linux box. Here's an except from my logs.

There's some more where it's basically saying that it can't read anything
from the modem. It then periodically tries talking to the modem, each looks

The really strange thing is that I can still poll using UUCP, and dial out
using minicom. So far my only method of fixing the modem to speak with
mgetty is to reset the computer. (A soft reboot works fine.)
Help! If you anyone needs more info just yell. :)
BTW, I added a few more \d's to the init-chat string because the FAQ
recommended it if you had timeout problems.
Thanks in advance!
