A couple of extra points about this: - Currently, ppbus headers aren't installed by 'installworld'. Should this be changed? - I have a sample program for talking to LCD displays hung off the parallel port (currently only supporting the HD44780 but designed to be extended) using the 'ppi' interface. Is this too specific for inclusion as a sample program? (I suspect yes, but others may disagree.) -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\
