Since this has come up several times recently, I have posted it for
general usage.  This was gotten from the net, and the original author
is quoted in the following:

The following script will do it (in a simple way).  Just add it to your
crontab file to call it every five minutes.

# screen saver for sco console

# Published on the net by Chip Rosenthel

# use who -u for logged in screens
# use who -a for all active screens
who -u | awk '{
	tty=$2				# basename of tty
	idle=$6				# time idle in "hh:mm"
	if ( tty !~ /^tty[01][0-9]$/ || idle == "." || tty == "tty01" )
	    next			# skip non-console & non-idle terms
	n = split(idle,x,":")
	if ( x[1] * 60 + x[2] > 15 )	# print tty if idle > 15 mins
	    print tty
}' | while read tty ; do echo "\f" > /dev/$tty ; done
