Wanted: SYS V.2 simple multisession software for dumb terminals

[Robert Andersson]

The title probably says it all. I am looking for software, PD, shareware
or commercial, that makes it possible to run multiple sessions from 
plain vanilla ANSI'ish terminals. 

Some facts:
o It must run under SYS V.2 (I have an NCR Tower 32/600).
o It can use pty's, since I have a SYS V.2 pty-driver that works ok.
o It doesn't matter if the software require adding device drivers
  to the kernel, or other low level stuff, I know how to do that.
o shl isn't good enough, I need something that can also run full-screen
  programs and that restores the screen as you switch sessions.
o I have looked at the "wm" program available from the usenet archives.
  It is far too Berkeley'ish, and doesn't seem quite finished either.

Reply by mail, I will summarize to the net if I receive more than two
useful replies. Oh, and please don't flood my mailbox with 'me too' 
type messages.

Thanx!
