stty rows=50; blank screen

On some of the machines we’re maintaining, the line
stty rows=50

works fine. On a another machine (HP Kayak XA workstation) the
same line causes the screen to go blank, forcing a reboot.

This unit has integrated video (doh!) is there a way to make this
work? What is it that differentiates video cards with respect to
this feature?

I tried starting Dev.ansi with / without -Q option; no dice.

The command you’re issuing fiddles with `standard’ VGA registers
to put the video card into 50 line mode.

You probably get the same thing if you just do >
and < . If it doesn’t work, or does bad things, then
I’d say that the card in question is not `standard’ VGA.
