Using the console screen protection feature

Using the console screen protection feature

VGA consoles can be set up to blank after a certain number of seconds to protect the screen from excessive wear. The kernel parameter TBLNK controls the VGA console screen protection feature. By default, screen blanking is not performed: to enable this feature, log in as root and use the configure(ADM) command or the Hardware/Kernel Manager described in ``Configuration tools'' in the Performance Guide. Select category 9, ``TTY and console configuration'' and change the value of TBLNK to the number of seconds that the system should wait before blanking the screen. Then relink the kernel as described in ``Relinking the kernel'' in the SCO OpenServer Handbook.
