C++ code to 68HC11 EVBU board

I am trying to send a code program written in C++ to a 68HC11 microprocessor on a EVBU board with a parallel port. I am trying to send bytes out the parallel port of the PC to the parallel port on the EVBU board. Having trouble sending bytes out of the parallel port so the 68HC11 sees hexadecimal value of byte. Any suggestions would be appreciated.

Which OS / Compiler are you using on the PC side?
What code are you using to drive the PC parallel port?
