I was thinking the [SysRq] would be part of the kernel in the form of a
key-action pair. The table would be loaded at boot time and would by-pass
running programs checking keyed input directly. That is what the LINUX
[SysRq] key sequence does. LINUX uses it for example to kill hung
processes.
It would also be possible to alter and manage the [SysRq] at the command
prompt with some simple program. Routines to carry out requested actions
are another issue. Something like simple sending end-of-print-job would be
a BIOS like routine that hooks the printer output.
Cheers.
