What's the best way to turn auto-answer on and off automatically at
specified times?  It's clear that cron does this job; what I seek is
an appropriate way to handle the modem.  I tried having cron just
echo the command sequences (e.g. ats0=0) to the modem, but that does
not work well for some modems: after a few cycles of this they get
out of sync with the system and require manual intervention even
though I am using hardware handshaking.
