As far as the restoring goes: don't restore the keyboard handler when you 
exit.  DJGPP handles the keyboard interrupt specially, so you shouldn't 
(and cannot) restore the previous handler; but the DJGPP exit code will 
do it for you.

That still doesn't explain why your program doesn't work, but that's 
another issue.
