- Are you sure that the pins you are reading and those you are writing to are the same ?
- Did you take into account that some of the pins are inverted (writing ''1'' sets them low), which may compound the problem above.
- Is your parallel port set for bidirectional I/O (BIOS option?)
- Other problems ?
