Blank monitor for an instant

[Mike Doty]

I'm looking for a way to send a signal to the video
monitor to blank the screen for a 1/2 second or so
while switching between screen resolutions, etc.
There used to be a way to poke a memory location.
Not looking to power off/on.

%ON = -1 : %OFF = 0
'=========================
Sub VGAoff(BYVAL BlankIt%)
'-- Turns VGA display on/off by disabling refresh
LOCAL disable?
if istrue(BlankIt%) then incr disable?
!  mov ah, &h12
!  mov al, disable?
!  mov bl, &h36
!  int &h10
END SUB
