How do you make a RS-232 cable to connect to a PC? Here's how I did it (not working): Coco RS-232 pin PC RS-232 (DB9 connector) pin ==================================================== 1 Carrier Detect/Ready 4 Data Terminal Ready 2 Data In 3 Transmit Data 3 Ground 5 Ground 4 Data Out 2 Receive Data I then disconnected 1 and 4 thinking maybe they weren't needed.
