In normal mode you can read 4 bit from the port while you have >8 bit in
output. In epp mode you will be able to read/write 32bit per time.
If you like to use the parallel port to do that you could take a look to
the list and search for the ppuser project that allow you to write that
kind of device also at user level without use ioperm() etc...
