fRtsControl = RTS_CONTROL_HANDSHAKE (RtsEnable?). Also, do I need to set
the handshaking? Below is the old and attempted new (that continually gets

I'm trying to send numbers over the serial port as bytes, not strings.

followed by a 5 and a 5. I'm trying to convert a borland c++ app.
This is what the c++ app does
int8B = 255;
WriteFile(serialPort,&int8B,1,&bytesWritten,NULL);
int8 = gainSlider->Position;...
