Are you writing the WJ8888 on your own, or are you using the Hamlib
backend to control the radio?

Care to contribute some code to the WJ backend?
If you're using some parts of Hamlib code, don't forget the license is
LGPL.

Try your luck on http://mods.dk, manual section, or maybe on premium
radio's web site.

Quick question: how do you hook up the SYNCHRONOUS IO to a standard PC?
To my understanding, PC's only have UART, which are asynchronous.

The sync-asynch would be the way to go. 
If the sync speed is slow enough, you may also play bit banging on the
parallel port or using the control signals of the serial port.
Some Hamlib backends are doing it for rigs controllable on SPI bus and
alike.
