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
