     NAME

          blanktime - sets the screen blanking timeout


     SPECIFICATION

          C         blanktime(nframes)

                    long nframes;




          FORTRAN   subroutine blankt(nframes)

                    integer*4 nframes


     DESCRIPTION

          The screen blanks (turns black) after the system receives no

          input for about 15 minutes.  This protects the color

          display.  blanktime changes the amount of time the system

          waits before blanking the screen.  It can also disable the

          screen blanking feature.


          nframes specifies the screen blanking timeout in frame times

          based on the standard 60 Hz monitor.  For software

          compatibility, the factor of 60 is used, regardless of the

          monitor type.  When calculating the value of nframes ,

          simply multiply the desired blanking latency period (in

          seconds) by 60.  For example, when nframes is 1800, the

          blanking latency period is 5 minutes. There are 60 frames

          per second; nframes is 60 times the number of seconds that

          the system waits before blanking the screen.  When nframes

          is 0, screen blanking is disabled.
