software engineer and did these things for a living. I would budget 2 to 3
days including reading the manual.

I was wondering why no one else suggested this. I did something similar
for the memory mapped displays on my 6809 way back when....
.. as for doing it on a VT it might not be as simple as it sounds. If
you are going to allow side-by-side windows you will need to keep a copy
of the window text in memory and re-write each window every time you
want to scroll the windows.

Overlapping would be amazing, different screen quadrants at a minimum. I
am going to try to port Txwindows as that is the only package I could

Thank you.
Screen is a linux utility. I am writing this on a bare metal (no
operating system) ESP32 dev board.
Right now the program is text menu driven. I would like to enhance it
with textual windows.
The Txwindows package is perfect but over kill and will need some
hacking to work in my environment and it doesn't support the VT-100's
region scrolling so screen updates might be slow.
What might be helpful is if you could be more specific about what it is
you're trying to achieve. Do you want arbitrarily sized, overlapping
windows or do you just want the screen divided up into discrete segments?
