Hello!

This is my first posting, so please forgive any mistakes.

I was reading through my PC manual  (Boy, isn't that a first :-) ) and
read about how there are different scancode sets available.  According
to my manual, it says that there are three sets,  Scancode set 1 (XT/PC
scancode), scancode set 2 (AT scancode, default), and scancode set 3 (??).

Does anyone know why there are different scancode sets and if there are
programs or accessories that use anything besides the default scancode set?
If DOS uses the PC scancode (which I think it does), why have all these
other scancode sets?  Anyway, how does this all work?

I'd be happy with just about any thoughts or insights into the matter.

Thanks!

PS  If anyone sounds interested, I'd be happy to share what I find out!
