My loads are pretty heavy. Did not see any problems with SSL yet.

import System.Posix.Signals

main =
     do installHandler sigINT Ignore Nothing
        x <- getChar
        if x == '\ETX'
           then do print "Gotcha!"
           else do print "Try again!"
                   main

This does not work for ^C. Can it actually be done? Of course I can  
just read "q" but that would be too simple :-).

	Thanks, Joel
