Chances are, the problem is in the switch settings within the modem, or
somewhere like it. Most modems are equipped with a switch to select the
response to DTR dropping low. If the switch is one way, DTR is ignored, and
you can't use it to hang up. With the switch the other way, DTR is obeyed,
and when you drop it (your ~. should do that) the modem hangs up the phone.
Some incompetents at Southwest Peripherals, Inc. in Phoenix fiddled
with the switches on 20 VenTel modems, when the factory settings were
correct, and caused a week of troubleshooting.  If there are no switches
on (in) the Racal-Vadic modem, try somewhere on your rs232 interface card.
