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<CR> doesn't work).  How
do I do this?  Also how can I detect if the modem is in 
command mode, for example if the line gets unplugged and I
get a NO CARRIER back how do I know to read that as a
command instead of data?  

 Thanks,
   Chris
