Greetings.

I am using a 2.4 Linux workstation in text mode (no graphic interface).
After some time, Linux activates the "screensaver" and the monitor goes 
blank on "stand by" mode until activity is detected from the mouse or 
keyboard.

Is it possible to disable this screensaver, so that the monitor keeps on 
all the time?

Thanks in advance.

Yes, but you need to send the screen some escape sequences, the
last time I checked. Subroutines included do the following:

noblank() Stops screen blanker (what you want).
scr()     Resets ANSI mode to return from shifted to normal.
           Sometimes the screen gets shifted after accidentally
           reading binary files.
cls()     Clear the screen.
