If it's possible, was there a driver/TSR which provide acces
to other monitor in multi-monitor setup? i.e. designed for use
by other program to specifically display things on non primary
monitor. Or a demo program which can use non primary monitor in
text video mode.

 
In a way, MS-DOS kind of had support for multi-monitors (2)
where you can flip between the two.
 
I had a B&W and a VGA and I was able to do this by using two
video boards.
 
Some Debuggers did support using 2 monitors.  Zortech c and
Microsoft 5.1 debuggers allowed for this.  The debugger would
show up on the B&W monitor where program output would show up
on the VGA.  This was on a 286.
 
So it was more up to the application as opposed to MS-DOS.

Sorry. I should have been more clearer.

I wasn't referring to multi-monitor provided by multiple video adapters.

I was referring to one video adapter which support multi monitors. i.e. has
at least 2 video output ports.

Mac, Windows, and Linux support multiple monitors on a single
IntelHD/NVIDIA/AMD video adapter, but so far, I've seen non primary monitors
used only for graphics video mode. I never seen any which is used for text
video mode. Though, may be I don't have enough experience working with
various hardware setups.
