Sounds to me like the config of your mgetty isn't right. I am not sure
how mgetty works, but if it is similar to normal getty it reads
/etc/gettydefs. In here is layed out the settings for the line once
mgetty starts up. One of the important settings it clocal. If this is
on, mgetty will ignore the carrier dropping. Once a call is received, do
an 'stty -a < /dev/...' Look at the clocal flag. If on, go and mess
around with gettydefs. If this is off, then a dropping carrier will
cause a SIGHUP to be sent to all the process on that port. This should
kill the mgetty and allow the port to be reused.

If you need more detailed help let me know.
