If you are using a standard modem, basically you have to open the COM port
to which the modem is connected, then to issue the following AT commands
(<CR> is the character 0xD, 13 decimal):

ATZ<CR>

wait for "OK" from the modem and then:

ATDT 0123456789;<CR>

Don't forget the character ";" (semicolon) after the number to dial,
otherwise the modem will try to connect in "data mode"

To terminate the call:

AT H0<CR>

Have a look at tapiRequestMakeCall().

Hi:
I have two modems: one internal connected to com3, and one usb external
connected to com4
(information from Device Manager)
I tried the following:

#include "stdio.h"
#include "bios.h"

void main()
{
int x;

FILE* comport;

if(!(comport=fopen("COM3:","w+")))
    perror("COM3 not open.");
else
{
    fputs("ATDT01555444333\n",comport);
}
if(comport)  fclose(comport);
}

I compiled and the response is:

COM3 not open.: No such file or directory

(I tried both "com3" and "com3:" ), the same thing happens to com4

any idea??
thanks
Maurice

"COM3" is correct

You might try using
HANDLE  h;
h = CreateFile( "COM3", GENERIC_WRITE, 0, 0,
		OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0 );
if( h != INVALID_HANDLE_VALUE ) 
{	DWORD	byteswritten;
	WriteFile( h,"ATDT01555444333\r",
		sizeof("ATDT01555444333\r")-1, &byteswritten, 0 )
	/*  also notice the change to \r  */
	CloseHandle( h );
}else{
	//handle the error
};

Hello:
thanks for clarifications
But which header file should be included in the beginning?
I tried "io.h", it didn't work.
I use always the free command line compiler.
that's what I've tried:

*******************************************
#include "stdio.h"
#include "io.h"
void main()
{
HANDLE  h;
h = CreateFile( "COM3", GENERIC_WRITE, 0, 0,
OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0 );
if( h != INVALID_HANDLE_VALUE )
   { DWORD byteswritten;
   WriteFile( h,"ATDT01555444333\r",
   sizeof("ATDT01555444333\r")-1, &byteswritten, 0 )
   /*  also notice the change to \r  */
   CloseHandle( h );
   }else{
   //handle the error
   };
}

Thanks
Maurice

We are in the .nativeapi group.
Those functions are native Windows API functions.
The vast majority of Windows functions are available by including
windows.h.

#include	<windows.h>

The headers for those that are not included by windows.h may be found
by looking at the documentation for the functions. MSDN is esspecially
good at that.	http://msdn.microsoft.com/library/

Thanks very much, it worked!!!!!!!!!!!!

Now, if you had time, I like to read the modem status to know if the ligne
is busy or not.

Any idea???

Thanks again
Maurice

After WriteFile() do a ReadFile() to read the response.

You would probably want to read single chars and build up a response
out of them because you don't know the size of the response ahead of
time.
