Basically its a parallel port display that uses the generic Hitachi HD44780 chipset. What the driver for linux does is provide a /dev/lcd that you can address the same as you would /dev/cuaaX for a serial matrix orbital display. The reason I am using the parallel port LCD, is that it cost $80, as opposed to $400+ for the matrix orbital serial display (I am in Australia). Shaun "Patrick S.
