Device::ParallelPort::drv::linux - Standard linux hardware io access
This is a basic driver that access the parallel port directly via standard io. This of course means that this script must be run as root (or setuid and all that involves).
You must be root to run this code.
This code uses a c portion that compiles in a assembler macro to read and write (via the kernel) to the address directly.
