Screen is primarily for multiple shells on a single VT-100 with
independent tasks/shells running in each window.
Since I'm not running an operating system and I really don't need
multiple tasks this doesn't look like it will meet my needs.
TxWindows looks the best of what I have found. I will have to try their
Linux version and see if i can pull out all of the operating system
stuff so that it runs with nothing more than a serial port driver.

Thank you...

Looks like version 3.9 was when they added split-screen support.

I really dislike the arduino environment but the base code that I
am using is written in it.
I also almost never use printf/scanf and its derivatives in
embedded code because printf/scanf are among the biggest space
hogs in the C library. I have written my own set of text input
and output routines that replaces all of the printf/scanf
functionality that I need in an embedded system.
Thank you for your advice. I will look into screen, if I an find it.

If this were my project, I would start by getting 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

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?
