If I am remembering correctly, the 3290 handled it's sessions itself,

Yes, the 3290 is a DFT, not a CUT, so it does multi-session MIS
(Multiple Interactive Sessions) style, not MLT-style. As I (now)
understand it, MLT is only for CUT (dumb) terminals, but DFTs use MIS.
In the
configuration, do you assign LU's to each 3174 port? I think you
need to assign extra LU's to the port that the 3290 is plugged into.
I had, yes, but it didn't get me anywhere.
In between cleaning, polishing, and setting up demos of running
systems for the big museum re-opening next weekend (will announce here
shortly, a few people have asked) I keep going back to the 3174+3290 and
fiddling. I'm mostly doing it in the dark...I have 3174 documentation,
but no manuals for the 3290's setup panels yet, and the parameters are
unlabeled. I've learned a lot, but still don't have any sessions
visible on the 3290.
What I've come to suspect is that the 3290 is actually working
properly, but there's something to do with terminal sizing or something
like that that's keeping the session selection screen from coming up.
This 3174 is a -61R with Ethernet and TCP/IP capability (Configuration
C), and it's set up to present a connection selection screen so the user
can select a host to which to connect. That has been configured and
working here, on several different CUT terminals, for a couple of years.
I'm just trying to add the 3290 to the mix. But that connection
selection screen just never appears.
My next step is to try to configure a static connection from one of
the 3290's sessions directly to a host in the 3174's configuration, and
see if that host's logon screen appears. If it does, then I'll know
there's something up with the way the 3174 wants to present its
connection selection screen.
