N short pulses increment a counter to position N
A long pulse toggles the N-th relay and resets the counter.
A dual singleshot, some gates, a counter and a decoder
-- that is all it would take.

On your PC side, if you use Visual Basic, I think you need a special version of it to control a serial port, do you?
