Hi, Right, I won't be using the port for actual STEP/DIR. They are made by the FPGA on the step generator board. In the modified code for CNC Pro it was a simple inp and outp to write the the generator board. If the "broken pipe" problem is simply something with the parport driver (and not deeper in Linux), then I think I can work with the problem. If it was in Linux, I'd be stuck.
Now to see if I can get the source coded down on to my computer and start investigating the parport driver.
