Does someone have C or Assembly source code that they could give me that
lets you abort the current program by hitting the SysRq key?

For example: Load the program as a TSR.  Debugging an application program
and it winds up in an infinite loop.  Hit SysRq and you're back in DOS.

I have something right now that is pretty crude, that almost works by 
hooking the Print Screen Interrupt and then calling Int 21, 00h.  The
problem with it though is that it doesn't clean things up.  It tends
to leave the aborted program in RAM.

Thanks in advance.

Bryan.
