Sorry i should probably have said the modem needs to be configured
right to work `the unix way'...

The modem's escape sequense is three escape symbols (usually '+') which
maybe disabled if the escape symbol is >127 (stored in register 2):
ATS2=x where x>127 disables it, so xxxATH0 won't work. It is good to
disable it (otherwise you get dropped with a simple ping...).

You have to control and respond to state changes yourself. There is no
"backchannel" available to tell you what's going on. More directly, there

Hi, I am currently writing a program that will use an attached
modem to dial and connect to a remote site to gather data. I
have been able to dial, connect, send data back and forth, but
I just can't seem to get the modem to hangup. I probably have
to bring the DTR low (+++ATH doesn't work).
