To a certain extent, yes.  A long time ago, I built a program called
"screen" on our suns here.  I can't remember where I got it, but it
does exist and work on machines with BSD support.  It's README file
begins:

"screen" is a window manager that allows you to handle several
independent screens (UNIX ttys) on a single physical terminal; each
screen has its own set of processes connected to it (typically
interactive shells).

Incidently, I rarely use screen because _I_ have job control.  :-)  I
only built it because there is no way to escape from and suspend a
decnet login like a telnet or rlogin (sun's dni software s*cks), and
that is rather frusterating when you're logged in from a 80x24
terminal.  Also, on PC's, NCSA telnet provides a similar "window"
system.  It is rather nice and fast.
