Of course it wont work - did you actually read my email the pin
connections are....
COM2 Header DB9 DB25
Pin 3 RS232 RXD pin 2 pin 3
Pin 5 RS232 TXD pin 3 pin 2
Pin 9 ground pin 5 pin 7
so a standard 1-1, 2-2, connector doesn't work.
And so far technologics have done nothing but add confusion to this.
Believe me make up your own cable with those 3 wires and it'll work.
