rare mode
     
         {Unix} CBREAK mode (character-by-character
        with keyboard {interrupt}s enabled).  Distinguished from {raw
        mode} and {cooked mode}; the phrase "a sort of half-cooked
        (rare?) mode" is used in the V7/BSD manuals to describe the
        mode.  Usage: rare.
