I am running SCO Xenix 2.3.2 on a COMPAQ 386 20 e .
I am trying to reach the terminal screen buffer :
I can access the Video RAM and read the data of the
current screen from the video RAM. Instead I would like
to access the display memory of any tty (tty01 - tty12)
which I think have a dedicated pointer somewhere on the
kernel, and read the data I need from that displays memory.
If this makes sense to you and you know how to do that
please let me know !!

Thanks
