WP34s Programming Cable

Very nice, Jonathan!

Here's the story on how to connect Tx and Rx.
Some computer equipment is classified as Data Terminal Equipment (DTE), like a computer, in which case Tx is an output and Rx is an input. Other computer equipment is classified as Data Communications Equipment (DCE) like a modem, in which case Tx is an input from the DTE and Rx is an output to the DTE. When two computers (DTE) are connected by a null modem cable the Tx and Rx signals are crossed.
When in doubt, check the datasheet for the component used.
