Keyword reference for bell

Just a small question, what is the bell character? i.e. the one that makes the terminal bleep? I was told it was BELL, but if thats true do we have to output it one letter at a time ?
No; `BELL' is a BYTE constant. Please refer to Question 13 (2003).

When we send the bell command to the screen is the internal speaker meant to beep, as mine doesn't. All I get is a symbol of a bell in the lower window. Is this correct? Thanks.
Unix shell windows (e.g. xterms and xvts) can be set to respond to the bell character (ASCII code 7) in several ways. These include:
That response is not up to your occam program - all it can do is send the character. Setting that response may be possible ... but you'll have to explore the idiosyncracies of your terminal emulator.
How do we get the terminal to beep? Is there a character we need to send?
See Question 18 (2000). One thing that answer didn't mention, though, is that you probably will also need to output a FLUSH to the screen channel (after sending the BELL). Otherwise, Unix buffers characters sent to the screen until either the buffer gets full or a new-line is output. So, if you want that beep straight away - rather than at the end of the current line of output - don't forget to FLUSH.
Reminder: please look through (and maybe print out) all questions and answers from previous years before re-asking them ...
