Not sure what you're trying to do, but for devices to talk to eachother
pins 2 & 3 need to "crossover" like this.

Device #1 Device #2
Connector #1 connector #2

pin #2 (transmit) ------------------------------- pin #3 (recieve)
pin #3 (recieve) -------------------------------- pin #2 (transmit)

Staight cables (what you have) are sometimes used in special cases -
like flashing EPROMs.
