The following program, written in Orca/C, was supposed to dial a phone
through my modem, but just printed "+++atdp18009991234" on my screen.
What do I need to do to dial through my modem?
#pragma keep "test"
#include <stdio.h>
#include <orca.h>
#include <stddef.h>
#include <stdlib.h>
#include <texttool.h>
main ()
{
DeviceRec olddevicerec;
long modemslot=2;
olddevicerec = GetOutputDevice ();
SetOutputDevice (basicType,modemslot);
WriteCString ("+++atdp18009991234");
SetOutputDevice (olddevicerec);
}

Remember several things though. 1) You'll need a carriage return after the command for it to be sent to the modem. 2) The default speed on the port might be higher than the speed of your modem. (Printing to a modem at 9600bps with a 2400bps modem doesn't work). 3) You might want to have the serial port firmware do a reset. This could bring the DTR up (if it was down), reset the parity, bits, speed to the settings in the control panel etc. 4) You might be printing to the modem too fast. Some "Hayes Compatibles" can't accept commands at the full rate their typed. (2400bps modems rarely accept commands typed at 2400bps!.. they expect some slow-ass typer to type the commands)... a pause between characters is sometimes helpful. 5) Remember that there needs to be a pause before and after the +'s, and a pause inbetween for the modem to work. 6) Download John Snow's (John?) SERINT and CSERINT routines. It provides a very nice, powerful, small "C" interface to the firmware. I speak from experience with GenericComm v1.0, v2.0 and now v3.0.
