I just posted in alt.sources some library code for Boreland C that can be
used to drive a printer port bi-directionaly.  This code is fast and
should do what you need.  Note that this library is NOT interrupt driven.
For the original application, we needed the speed of polled mode.  An
ISR should be trivial to use Boreland's ISR routines. 

If there is interest, I'll post it here too.
