Hallo everybody,
I have modified the keycode remapping table in drivers/tc/lk201-remap.c
to deliver PC compatible keycodes. Aim of this modification is easier
use of XFree86 on DECstations (with the standard PC-keyboard map) and
the possibility to use existing loadable national keymaps for i386.
In theory, this should work, in practice, it does not :-(.
I have encountered several problems when running the new remapping table
with a standard i386 us.kmap.gz:
- the "Alt Function" keys on an LK401 seem to deliver no keypress event
(same behaviour with the original DECstation mapping, so this
seems to be a generic problem. Does the LK401 need a particular
initialization to use these keys (which do not exist on an LK201)?
- When running in console mode, everything besides console switching
(because of the missing ALT-keycode) and activating NumLock (keypad
is always in cursor mode) works. In XFree86 the normal character
keys and the main keyboard number keys work fine, but cursor keys,
the Del/Insert/Pos1/End/etc. block and the numeric keyblock do not
work at all or deliver wrong keycodes.
I would be very grateful if somebody could give me a hint about the
reason for this behaviour, the modified lk201-remap.c is attached to
this mail.
Regards,
Karsten

* PC-compatible keyboard mappings for DEC LK201/401/501 keyboards
* 2002/02/09 by Karsten Merker <merker@linuxtag.org>,
* based on the layout of the original lk201-remap.c written
* 17.05.99 by Michael Engel (engel@unix-ag.org).
* This file is subject to the terms and conditions of the GNU General
* Public License, version 2. See the file "COPYING" in the main
* directory of this archive for more details.
*
* Rationale:
*
* DEC US keyboards generate keycodes in the range 0x55 - 0xfb
*
* The (historically PC-centric) Linux keycodes have to be in the
* range 0x00-0x7f, so the raw keycodes from the keyboard have to
* be remapped appropriately.
*
* This remapping table in contrast to the original lk201-remap.c (which
* numbered the keys by their position from top left to lower right)
* delivers PC-compatible keycodes.
*
* Relocated keys (from a PC-keyboard point of view):
* SysReq/ScrollLock/Pause are on F13/F14/Help
* Pos1/End are on Find/Select
* ESC is on Do
* LeftPenguin/RightPenguin are on LeftCompose/RightCompose
* Menu/RightControl are on F17/F18
* The numeric keypad has PC-like layout
