This file lists the values of the framebuffer parameters that Screen is using.
The win-0 file in /dev/screen/0/ shows the configurations of the framebuffers that Screen is currently using.
From your target, you can see the configurations of the framebuffer that Screen is currently using by looking at the win-0 file in /dev/screen/0/win-0. The values you see from this file are the values that are currently used at the moment when you cat the file.
For example, you can use this command from your shell:
# cat /dev/screen/0/win-0/win-0
to see the framebuffer parameters currently used:
