Access directly to the parallel port under linux is only possible if you are 
part of the kernel... ie- you need to patch into the kernel to pull that off... 

Why not take a look at this package:


It shows both methods of accessing the parallel port, user space and kernel 
space. Even if you decide not to use this package, it will at least get you 
started in the right direction.
