ZBEEP doesn't work

ZBEEP doesn't work

[Han Pingtian]

Hi,

I have tried to set ZBEEP to "\e[?5h\e[?5l" according to the manual, but
it doesn't make the terminal flashing. Because it's too quick the
reverse video on and off. If I run a command like this:

% print -b '\e[?5h';sleep 0.05;print -b '\e[?5l'

then there is a flashing on the screen. 

So what can I set in ZBEEP for a screen flashing?

Thanks.

That way of doing things is certainly a bit VT100-age.

If your terminal has a visual bell, you're better off using that. xterm
and rxvt do but I haven't checked the various GUI system terminal
emulators.  The option is -vb and the resource is visualBell.

ZBEEP='\eg' # should "ring the visual bell"

Alas even that often doesn't work, I suspect the graphical display driver
on top of which the entire windowing system is running, optimizes out any
changes that occur between refreshes.
