Gee...I can't figure out a nifty-neato way of including the relavent
part(s) of previous posting(s).  Anyway, about hanging up the modem -
The reason +++ATZ doesn't work is because there must be a delay both
before and after the +++.  The delay is specified by an S register (sorry,
I don't have my modem manual here so I don't remember which) usually a
second will do.  As for dropping DTR, this only works if the switches
on the modem are set to "FOLLOW DTR" ie - they must not force DTR on.
Many modems also have software commands to follow/ignore the DTR signal.
