If you want to use NCURSES / CURSES, it's a bit complicated.
Otherwise, just output %c (the character) 0x07, BEL, which
generates an audible bell, or beep.

Instead of a beep and a flash I get:

HAMOR
on the console.
Hamor is a tcsh prompt.
Maybe something is wrong with my installation?
Or maybe I'm too stupid and missed something
obvious?
thank you

Doesn't seem to do anything. Maybe

But mp3 player seems to come out ok.
Or maybe I missed something obvious..

That sounds about right, given the code shown above.
If you'd used just
beep();
refresh();
instead of the printf/fflush, it would clear the screen and beep - if the
terminal description says it can do the beep.
In the ncurses sources, progs/clear.c is a simple program which sets
up the terminal and calls the tputs function - something like what you're
trying to do.
