We are looking for something that would allow a user to switch
between several processes. This will require an update of the screen
every time the user select a new process. Since we want this to work
with any kind of software written for SysV, we can't relay on the
software for doing the update. This means that we need some kind of
screen-image of every process kept in memory, wich will be dumped on
the screen before a new process is attached to the terminal. It
isn't possible to make the terminal send it's screen back to the
system. Besides the screen-image, we need a copy of the current
stty settings.

We know that some parts of this can be solved using shl, but how do
we manage the updating of the screen-image?

We are using a NCR Tower-32 and a Tower XP with SVR2.

Anything that has just a little connection to this problem is very
appreciated.
