:feep: /feep/ 1. n. 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. vi. 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}.
