This could cause heart attacks! Another couple of data points: Running python 2.3/MSVC6 or python 2.4/MinGW in an NT4 console window, print '\a' beeps via the PC internal speaker (like winsound.Beep). Running the bash shell of msys, echo -e '\a' also beeps via the PC speaker. These are not affected by any volume control that I know of. But running py2.3 idle, print '\a' displays a square empty box (which I take to be the symbol for unprintable characters). That seems like an oversight in terminal emulation.

Re: System bell
Serves me right for blindlyrunning things from IDLE.
This does work (tested on WinXP only):
import os
os.system('echo \a')

The IDLE stdout/stderr handling is not invoking a system bell when it sees '\a'. I suppose that one could consider that a bug. If I were an IDLE developer/maintainer, I don't think I'd rate that as a very high prioirty bug though. :) Trent -- Trent Mick [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list

I suspect that you are misinterpreting failure as success here. This is
probably only resulting in a bell from the shell when it complains that
it doesn't know of any command called \a to run.
