I'm trying to send modem dialing commands from DOS to
trigger a pager. (Modem=USR 56K Fax PCI on COM3, WinXP
Home). I would like to send ATDT 18881234567,,,,124124#
to the modem from a DOS Batch command.
From DOS Prompt:
ECHO ATH1 >COM3 correctly takes the modem off hook and a
dial tone can be heard.
ECHO ATZ > COM3 correctly resets the modem.
But:
ECHO ATDT 12345 >COM3 causes a short crackle from the
modem speaker as if it briefly tries to go off-hook and
immediately hangs up, but doesn't send any dialing tones.
Modem works normally in all Windows Apps, and responds to
ATDT dialing commands using HyperTerminal.....
Any ideas on what I'm doing wrong appreciated!
