TC1000 has two keyboards - technically. There is standard AT keyboard=20
controller with four side keys/buttons, somewhat hidden reset key, and a jo=
g=20
dial (Left, Press, Right). Scan codes produced are as follows:
'Outlook' =9A =9A =9A e0 02 =9A =9A =9A =9A =9A e0 82
'CompaQ' =9A =9A =9A =9Ae0 03 =9A =9A =9A =9A =9A e0 83
TAB =9A =9A =9A =9A =9A =9A e0 04 =9A =9A =9A =9A =9A e0 84
ESC =9A =9A =9A =9A =9A =9A e0 05 =9A =9A =9A =9A =9A e0 85
Left =9A =9A =9A =9A =9A =9Ae0 06 =9A =9A =9A =9A =9A e0 86
Press =9A =9A =9A =9A =9A 1c =9A =9A =9A =9A =9A =9A =9A9c
Right =9A =9A =9A =9A =9A e0 07 =9A =9A =9A =9A =9A e0 87
Ctrl-Alt-Del =9A =9A1d 38 e0 53 =9A =9A 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=20
keyboard attached via USB works well. Scan codes are another story - with n=
o=20
other changes, only Press (like Enter) and Ctrl-Alt-Del (like=20
Ctrl-Alt-Del :) ) works. As there is no point using TC1000 with no (either=
=20
detachable or standard) USB keyboard, I think the best way is modify kbdmux=
=2Ec=20
to recognize TC1000's non standard scan codes. I used this patch:

I would like to get this into source tree - at least Maxim has no objection=
s,=20
however, maybe making this patch an option would be good, too, but I have n=
o=20
idea now, how to do it, exactly.
As both 'Outlook' and 'CompaQ' keys start an application under Windows, I=20
decided to send a notification from kernel, so a user level script could be=
=20
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=
=20
with this patch one can create both console text-mode and X configuration.

Milan
