Ah, direct port access for the parallel port. While this is definitely
the way that works independent of the operating system (as it works
around the operating system), it is a pity to use this on operating
systems that have a clean parallel port bitbang interface. It happens to
be the case that Linux does support parallel port bitbanging
using /dev/parport. Any chance to use OS-specific parallel port
interfaces where possible?
