[comp.os.cpm] ?Wyse & Televideo attributes & modes

bridger@RAND-UNIX.ARPA (01/13/87)

Does someone with hands-on experience with the Wyse 50...
and Televideo 9xx... series terminals know how to determine,
from a program that is running on a host computer attached to one
of those terminals:

1. what screen attributes are active, in which locations of the
   screen?

2. what terminal modes are active, especially # columns, and text
   segment?

In order to complete a BackGrounder ii screendriver for this group
of terminals I'd like to be able to restore the current screen
attributes when the screen gets redrawn.  The manuals do not
seem to include commands to transmit attribute or mode information
to the host.
