Console video sleep mode?

[Ron Johnson <ron.l.johnson@cox.net>]

Hi,

(I've tried Googling, but all hits seem to refer to various laptop 
suspend modes.)

When in "console mode" (i.e., no X!), and no one is logged it, the 
screen blanks after 10ish minutes, but the monitor stays fully 
powered.  How do I tell the screen to go into sleep mode?

Thanks
