OK.... here's the question of the day....

I have a Windows 3.0 Communcations package I am writing and I need to hang the
modem up after the communications session has ended.  Using a MultiTech 9600
Baud v.32 modem I get the attention of the modem by sending three plus signs
and then an "ATH0<CR>" and the connection is terminated.

The problem:
When I use a normal 2400 baud modem to make the connection, I still get the 
modems attention, but when I send the modem the "ATH0<CR>" I get no 
response from the modem and the line does not hang up.  

Side light: Does anyone know how to drop DTR on a com port in Windows????

Any help is appreciated very much..... Steven Poling
