Program to control the modem
Program to control the modem
(OP)
Hi,
I'm trying to find out how to write a program to control the modem to dial telephone number. What I've found so far seems to be related to interfacing the PC to the modem, but stops short of saying how the dialling is done. Anyone can point me in the right dirction?
Thanks!

If your not interfacing with the modem through a PC, I don't know.

RE: Program to control the modem
the only way that I have ever heard of being able to program a modem is through the serial port, be that a physical one such as RS-232 or through a virtual port supported by the operating system. To control the modem you use the AT command set as Gerald pointed out. To get a modem to dial you issue the command AT DT 555 1234. The 'D' tells the model to dial, and the 'T' tells it to use tones (as opposed to 'P' for the old decadic pulse dialing). The modem will respond back with a 'CONNECT' message when it has successfully dialed the other party. You can then send whatever charaters you want to the serial port and onto the other end.
Hope this helps.
