reading this, leads me to a simple question.
i´ve made a little user-space driver (plus some higher level library functions)
to connect an old lc-display to the parallel port.
does the parport driver provide an API to control the data and ctrl lines of the
parallelport directly, so i can make my driver hardware independent?
latly i had to read the 132 pages long documentation of my chipset, to find out
how to switch to PS2-mode. ;-)
