DSP Robotics Support

Greetings to all,
This question will probably already been asked several times but could not find anything in the database.
I come from alternative programs to Flowstone, I have the need to use the parallel port as input and output data (single bit 8 = out and 4= in), there is a practical example, if is possible?
thanks
Bufere

I only work with audio, so am not the best to answer. But it seems there is no access to the parallel port.

Maybe the Robotics forum could help...?
