Our system is running SCO Xenix 2.3.2, with a Hayes modem off COM1:
or {tty1a,tty1A}. We use it as a dialin/out modem, and occasionally,
the modem does not reset itself properly after attempting to dialout.
Until it is reset, it will not answer the phone again.
I just wanted to share this information with everyone. Put the following
line in your '/usr/spool/cron/crontabs/root' file. (This will reset the
modem on port tty1A if it's not in use, and wont disrupt any process if
it is in use):
/bin/kill `ps -e | sed -n '/? 0:0. getty/s/^[ ]*\([^ ]*\).*/\1/p'` >/dev/null
I have my cron run it every 5 minutes.
