writing a keyboard driver

[Justin C. <jp...@do...>]

I am just sitting down to write a kernel module for an Apple Newton serial
keyboard,a nd I am slightly confused by the terminology about scancodes.

1.7 The keycode, keycodemax, keycodesize fields
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

These two fields will be used for any inpur devices that report their data
as scancodes. If not all scancodes can be known by autodetection, they may
need to be set by userland utilities. The keycode array then is an array
used to map from scancodes to input system keycodes. The keycode max will
contain the size of the array and keycodesize the size of each entry in it
(in bytes).

What does this actually mean? Should I use this? Could someone just quickly
explain...
