... it works on my TabletPC TC1000. Many thanks, I think this is a must
for every notebook/similar device user.
TC1000 has two keyboards - technically. There is standard AT keyboard
controller with four side keys/buttons, somewhat hidden reset key, and a jog
dial (Left, Press, Right). Scan codes produced are as follows:
'Outlook' e0 02 e0 82
'CompaQ' e0 03 e0 83
TAB e0 04 e0 84
ESC e0 05 e0 85
Left e0 06 e0 86
Press 1c 9c
Right e0 07 e0 87
Ctrl-Alt-Del 1d 38 e0 53 9d b8 e0 d3
Detachable USB keyboard (with pointing stick working like USB mouse) works
well. In that situation, using kbdmux is the best solution - even another
keyboard attached via USB works well. Scan codes are another story - with no
other changes, only Press (like Enter) and Ctrl-Alt-Del (like
Ctrl-Alt-Del :) ) works. As there is no point using TC1000 with no (either
detachable or standard) USB keyboard, I think the best way is modify kbdmux.c
to recognize TC1000's non standard scan codes. I used this patch:

break;
(please unwrap what's necessary, use tabs instead of spaces where applicable).
I would like to get this into source tree - at least Maxim has no objections,
however, maybe making this patch an option would be good, too, but I have no
idea now, how to do it, exactly.
As both 'Outlook' and 'CompaQ' keys start an application under Windows, I
decided to send a notification from kernel, so a user level script could be
fired. Relevant dev.conf lines could be
notify 0 {
match "system" "TC1000";
action "/root/test $subsystem $type";
};
Today I discovered a way to go with those kays undex X and verified it, so
with this patch one can create both console text-mode and X configuration.
Regards,
Milan
