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.

I am doing the same thing and I cannot get the modem to turn Auto-Answer back on. It doesn't seem to pay attention to the Dialers line with the "&". Any help would be much appreciated.

You can simply turn auto-answer off as part of your dialing routine (don't save with &W), and when the session is complete DTR drops momentarily and your saved defaults restored. There was a bug in the dialer source code on Xenix 2.2... This bug was in the hangup processing (-h option) issued after you were through. I forget the exact details, but I think the dialer would fail if it didn't receive on OK response to +++ to wake up the modem. This would leave the line with the DIALOUT login requiring system reset or diddling either /etc/wtmp or /etc/utmp (I forget which). I could probably find my patched version of the dialer I used before switching to dialTBIT.c -- ....microsoft--\ Bill Campbell; Celestial Software ...uw-entropy----!thebes!camco!bill 6641 East Mercer Way ....fluke------/ Mercer Island, Wa 98040 ....hplsla----/ (206) 232-4164
