Say Y here if you have an HD44780 or KS-0074 LCD connected to your
parallel port. This driver also features 4 and 6-key keypads. The LCD
is accessible through the /dev/lcd char device (10, 156), and the
keypad through /dev/keypad (10, 185). This code can either be
compiled as a module, or linked into the kernel and started at boot.
If you don't understand what all this is about, say N.
