Need code for screen flash (vt100 'vb')

[Mark R. Lindsey]

Does anyone here know how to make the screen flash? What procedure for
making it do so should I employ?

Thanks.

Here is a lovely little prog that will do it for you. Save it as something,
and then run it, with the shell to be 'flashed' and the time in between
flashes
i.e, flash ttyp 1

Hope it works!

#! /bin/csh -f
while 1
echo -n "[?5h" > /dev/$1
sleep $2
echo -n "[?5l" > /dev/$1
sleep $2
end

Flicking the power switch 20 times in rapid succession.

On System V machines you can use ``tput'' to generate any of the
control sequences which are defined for your ``TERM'' terminal type.
GNU has a ``tput'' utitilty which you can get the sources to.

So to write ``this is a test'' in reverse video (regardless of
the terminal type), you can execute this:

$ tput rev ; echo "This is a test"; tput sgr0
