How can i produce a long beep ONLY (no 3rd tools) with the cmd? (only one cmd command)
I know ^G - but there isn´t any duration. Its only a short beep.
You can loop and repeat the echo ^G (BELL Char)
Duration will depend on your hardware.
And you could alternate calls to the color command to have the window flash as well.
Also you can create a set of ascii file with just the number of bells you want and do a type on it.
