Thread: Nokia datacable using COM1

Totally operating system dependant.
On windows you can use CreateFile(). Check out the docs at msdn.

If it accepts ascii values like a modem, then you can open the com port as a file, but the downside is that you only get simplex communications.

Code:

#include <iostream>
#include <fstream>

using namespace std ;

int main()
{

        char port[10] = "COM1:";
        char character;

        
        ofstream comport (port);  // open port as file


        if (comport.fail()) 
        {
                cout << "ERROR-Unable to open " << port << '\n' ;
                return 1 ;
        }

        comport << "ATD123,,4567,,";

        // any pause function... ie getchar()


        comport.close();

return(0);

}
