When GNAT for DOS/Windows (yeah, a while ago - remember Ada9X?) did 
this, I used a 'wimp out' solution:

    function KB_Hit return Boolean;
    pragma Import(KB_Hit, "kbhit"); --not sure of the syntax
    ...
       exit when KB_Hit;
    ...
   (of course you have to remember to Flush or equiv)

Not pretty, but it worked.
