''***************************************
{-----------------REVISION HISTORY---------------------------------
v1.0.1 - Updated 6/15/2006 to work with Propeller Tool 0.96
------------------------------------------------------------------}
{-----------------KEYBOARD LAYOUT HISTORY--------------------------
2009-08-31 (Y-M-D)
Patch for german keyboard layout
Author: oog
Added german keyboard layout.
Original layout is commented as keyboard-us-en (US-English).
German layout is commented as keyboard-de (de = deutsch = "german").
Now there are two tables for keys with and without SHIFT-Key.
It should be easier to implement different international layouts.
However, it's bigger now and uses more memory.
2009-09-05 (Y-M-D)
Fixed bugs
- code bug on home-key fixed
new replace-codes for de_ae, de_ou and de_ue
New
- Documentation of control-key bits
This should be helpful for translat<00>ons of this driver into
different languages.
- table_alt_r
This table contains characters for the german "AltGr" key.
- AltGr+F1..F12
Returns line-characters, selected from $90..$9f
2009-09-06 (Y-M-D)
Fixed bugs
- patch table_shift for "?"
Differences to Parallax driver:
- Different codes for NumLock, CapsLock and ScrLock to avoid
conflict with german "<00>"
Codes are defined as constants and easy to change
- Easy Cursor codes implemented to avoit conflict with the "<00>"-key
Easy Cursor codes are easy to understand,
for example "Cursor Left" is the character "<00>!"
