Can this be done from command line (eg. "dd" with skip=... etc)? I saw a lot of people (when I was a pupil some time ago) who bought easily buildable inferfaces for their parport (resistor->transistor->relais...) and tried to access it via dd (they never learned C or any usable programming language at all) and _randomly_ crashed their system. So I tested and found the problem in missing seeking capabilities. However, I think that /dev/ports is quite oftenly used this way;(
