I had a similar problem setting up Linux with my old modem. Look in
your modem manual for the S register (I think it's S25) which controls
how long the modem waits after DTR drops before hanging up. Often
the factory default is quite short, so any tiny glitch on the DTR
signal will cause hangups like the one you see. Set S25 to a larger
value (20 causes it to wait 200ms; 50 gives a half-second timeout) and
I'll bet your problem is solved. Don't forget to save the value into
the modem's NV RAM.
