ASCII 7, ASCII mnemonic "BEL", the {character code} which prodces a standard audibile warning from the comPUter or terminal. In the teletype days it really was a bell, since the advent of the VDU it is more likely to be a sound sample (e.g. the sound of a bell) played through a loudspeaker. Also called "G-bell", because it is typed as Control-G. The term "beep" is preferred among some microcomPUter hobbyists. Compare feep, visible bell. (1997-04-08)
