Look up bioscom in your help file, it gives you everything you need to make a simple modem program...

#include <bios.h>
#include <conio.h>
#include <iostream.h>

#define COM1       0
#define COM2       1
#define COM3       2
#define COM4       3
#define DATA_READY 0x100
#define TRUE       1
#define FALSE      0

#define SETTINGS ( 0xE0 | 0x02 | 0x00 | 0x00)

void put_one(char t)
{
      bioscom(1,t,COM1);
}

void put_line(char line*)
{
      int ctr;
      for (ctr=0;ctr<sizeof(line);ctr++)
            put_one(line[ctr]);
      put_one(13);
}

int main(void)
{
       int in, out, status, DONE = FALSE;
       char *number;
       bioscom(0, SETTINGS, COM1);
       cout << "What is the number:";
       cin >> number;
       put_line("+++");
       put_one('A');
       put_one('T');
       put_one('D');
       put_one('T');
       put_line(number);
       while (!DONE)
       {
                  status = bioscom(3, 0, COM1);
                  if (status & DATA_READY)
                         if ((out = bioscom(2, 0, COM1) & 0x7F) != 0)
                                    putch(out);
                         if (kbhit())
                         {
                                    if ((in = getch()) == 27)
                                           DONE = TRUE;
                                    bioscom(1, in, COM1);
         }
       }
       put_line("+++");
       put_one('A');
       put_one('T');
       put_one('H');
       return 0;
}
