End product would ideally appear to the PC as a serial port with 
standard drivers, but needing drivers is permissible if necessary.

Data speed is subservient to lowest cost.

Output to drive a dumb serial port.

Best candidate so far appears to be something like the AVR309 
implementation using an ATtiny2313.
Processor, crystal, regulator, 3Cs, 1R, connector.

Any advance on that or comments?
