Not all terminals produce a beep when they receive a BEL character.
Many X11 terminals used to flash the entire terminal window instead
(otherwise you had no way to know which terminal caused the "beep").
I just tested three of the terminals on my laptop, and none of them
beep when they receive a BEL.
