Super!  This all works great!
Am I correct in assuming that WriteFile cannot pass an INT?
Where "phase" and "motor" are INTS and "coil" is a CHAR,
This code works:

         // Coil Off
         WriteFile(hComm, "w", 1, &dwWritten, NULL);
         coil = ((phase[motor] + 2) % 4) + (motor * 4);
         WriteFile(hComm, &coil, 1, &dwWritten, NULL);
         WriteFile(hComm, "\xo", 1, &dwWritten, NULL);

Is this the best way to handle it?
