I have had similar problems. A partial victory might be achieved by setting
your modems to reset on a dtr change. I.E. ATD0 I believe. Thus, when the
getty drops the line (dtr low) the modem performs an ATZ on itself and
resets back to 2400 baud. This has worked somewhat well on my machine but
sometimes the modem just loops on itself and continually resets for hours
until someone turns it off. I am using a Hayes 2400 external on an 
Altos 2086 running Xenix. If someone else has a more elegant solution
I'd sure like to hear it.
