Well, the problem may be that your modem is looking at DTR when
it accepts the dial string.  When you tell HC to dial a number,
it opens the serial port, asserting DTR along the way, sends the dial
string,  and closes the serial port (de-asserting DTR).  If your modem
is counting on DTR, then it will stop when it is de-asserted.  You may 
have either a switch on the modem or a AT command that will tell it
to ignore DTR.
