feep
     
        /feep/ 1.  The soft electronic "bell" sound of a display
        terminal (except for a VT-52); a beep (in fact, the
        microcomputer world seems to prefer {beep}).
     
        2. To cause the display to make a feep sound.  ASR-33s (the
        original TTYs) do not feep; they have mechanical bells that
        ring.  Alternate forms: {beep}, "bleep", or just about
        anything suitably onomatopoeic.  (Jeff MacNelly, in his comic
        strip "Shoe", uses the word "eep" for sounds made by computer
        terminals and video games; this is perhaps the closest written
        approximation yet.)  The term "breedle" was sometimes heard at
        SAIL, where the terminal bleepers are not particularly soft
        (they sound more like the musical equivalent of a raspberry or
        Bronx cheer; for a close approximation, imagine the sound of a
        Star Trek communicator's beep lasting for five seconds).  The
        "feeper" on a VT-52 has been compared to the sound of a '52
        Chevy stripping its gears.  See also {ding}.
