    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.
