1.1     ! mspo        1: To blank your screen on the console, the command [screenblank(1)](http://netbsd.gw.com/cgi-bin/man-cgi?screenblank+1+NetBSD-current) is what you need. It is part of the base system, so you don't need to install it. 
        !             2: 
        !             3: # screenblank
        !             4:     
        !             5: 
        !             6: This will activate blanking with a default of 600 Seconds (10 Minutes). If you wish to activate it in another time interval use the -d Option. 
        !             7:     
        !             8:     # screenblank -d 300
        !             9:     
        !            10: 
        !            11: #  Known Problems 
        !            12: 
        !            13: If you are using screenblank on a filesystem that is mounted with noatime/nodevmtime (such as a system running off of a compact flash card), screenblank will not properly time out when you set -d, nor will it receive keyboard inputs to wake. Often on small devices that do not have a hardware method of turning off the screen, this can be problematic and actually lock you out of a session until you reboot. Thus, the following is a known "safe" method for blanking a small devices screen even with noatime/nodevmtime: 
        !            14:     
        !            15:     #!/bin/sh
        !            16:     /usr/sbin/screenblank -d 0 -e 0 && read
        !            17:     /usr/bin/pkill screenblank
        !            18:     
        !            19:
