The wiring for your serial port seams not to be right. You should be
connected to pins 2 and 3, not 3 and 4. They should be tx and rx not rx and
cts. You don't need the flow control pins connected to each other, just set
it up in your app on the PC to use no flow control. All you need to connect
to the serial port to get it working is pins 2,3 and 5.
