bummer.  That was what I was worried about.  ok, thanks Steve. 

Actually, the TALK I remember from the Sys/34 worked pretty well.  Messages
travelled back and forth properly and the panel scrolled the text, just like
a real messaging program.  The huge drawback was you couldn't really page
anyone.  You typed TALK, and the next user to type TALK was connected to you
  If you wanted to TALK to Alice you had to phone her and tell her to type
TALK.

Of course that was... 20 years ago?

Booth -
 
I remember working with a couple of MAPICS MRT programs on the S/34. Talk
about *UGLY* and hard-to-maintain code!
 
To work like on of the old-style MRT programs, your TALK program would have
to use the ACQ (Acquire) operation to allocate the devices, and then the
application could be running as you envision. I don't believe you can use
ACQ to acquire a device unless it is *not* currently in use, and then *your*
application has exclusive control of the device.
 
IIRC, I don't think this is possible unless you assume that the user(s) on
the other terminal(s) sign off first. And then how would you know which
terminal(s) to ACQuire? This is not very workable in the real world.
