wy99gt with mscreen

[Ronald Florence]

We use a Wyse wy99gt on one serial line of a Xenix system.  Currently,
the terminal is run in vt220 emulation mode, both for GNU Emacs, and
to enable an easy switch in and out of Tektronics 4014 mode for
graphics.

We would like to enable page-switching of the terminal memory to use
the terminal with the mscreen feature of Xenix 2.3.2.  The
/etc/mscreencap includes entries for using the wy99gt in "native"
mode, with two pages of memory.  Is it possible to shift from native
mode into and out of Tektronics mode?

If not, is there a way to switch pages of terminal memory in vt220
mode for use with the mscreen program?

Thanks in advance for any help.
