If this were my project, I would read the VT100 manual and design and
implement a serial driver and basic text window library from scratch
running on the bare hardware. It wouldn't be more than 1000 lines of C,
more likely something like 500 lines. I am a retired embedded
software engineer and did these things for a living. I would budget 2 to 3
days including reading the manual.

newlib going and then
seeing if I could use that to run an older (presumably more simple, with
fewer requirements) version of screen.

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
find

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?
