Keyboard layout/scan codes

[Craig Andrews]

Hi all,

I am writing (or rather, intending to write) some kind of driver for a
custom 24 key keypad manufactured by the company I work for.

The basic design of the keypad is that the numeric keypad, the f1-f4 keys,
and a few others are used. This is controlled by the flash ROM inside the
keypad controller itself. However, I need to get a) a couple of keys which
appear as 'y' and 'n' when numlock is off, and '+' and '-' when it is on.
Also, the number 5 on the keypad needs to have an unshifted mode. At the
moment, nothing is returned when numlock is off.

I know this isn't an ideal situation, but the marketing department decided
on the idea and sold it to several customers before I even new it was in
planning. <insert random abuse about marketing here>

So, any ideas how I might start? I had a search on the web, and the best I
got from anywhere was 'hack the keyboard dll's with a hex editor'. OK, but
not a really good idea for a production system which should work RELIABLY :)
Also, doesn't address the keypad 5 issue.

Any help would be --greatly-- appreciated,

thanks
