I'd like to be able to switch the monitors on a number of
our computers into standby mode from a software program
running on a virtual console; and wakeup either when a key is=20
pressed or when the program has new information to display.
I can probably manage to control blank screen savers but I
would prefer to power down the displays to standby modes.
The machines are those small size 'kitchen computer' VIA=20
based cubes (almost). The monitors are LCD displays.
Are there ioctls to help with this?
How do I go about it?
All ideas welcomed.
Malcolm Kay
