If you prefer to not deal with assembly in Pascal to access bit mapped
registers, then use 'btrix' variant records.  A good review of how
to do this is in a back issue of Byte (last fall sometime).  It
tells how to access the micromodem, but the variant record concept
carries over very nicely to other peripherials.
