1 root@red:~# showkey
kb mode was XLATE

press any key (program terminates after 10s of last keypress)...
keycode 28 release
keycode 56 press
keycode 84 press
keycode 84 release
keycode 56 release

The 28 I believe the release from the enter key?
The 56 is the ALT key I think, and the 84 is SysRQ. So, it is
the right code. Any other ideas?
