Below is the entry for the FAQ on the subject, note that it is a draft
so it still needs to be cleaned up.  The cron solution of finding
getty is a recommended on.

37. Under 2.0 running UUCP and other dialins conditions hangs the dialup line,
  what can I do? (draft)

  There is a bug in the serial driver which causes getty to get stuck.
  The situation arises after a successful uucico connection, subsequent
  connections via modem will get a connection with the modem, but no
  login prompt.  This is caused by getty hanging.  A simple work around
  is to have a process run in cron to reset the getty every 15 minutes:

  #! /bin/sh -u
  PIDS=`ps -ax | bm getty | grep -v bm | awk '{print $1}'`
  kill -TERM $PIDS

  Of course trying to connect when the script is running will not allow
  you to connect, try again a  minute later.  This fix will not affect
  on-going UUCP or interactive connections.  This will probably be fix
  in the next kernel release.
