Here is a little niftyness from the people who tried to bring you
the UNIX-PC [and failed for the most part]

In SVR3.1.1 for our system they have added two switch codes
to the possibilities for a Dialers script.

	\M	Set CLOCAL
	\m	unset CLOCAL

you take you auto-dialing modem and set it to only pass CD when there is
carrier.

you then dial by:

set CLOCAL
dial the number
when you get the answered unset CLOCAL
 this effectively makes 2-way hayes compatible modems possible.
