We've been experiencing a flow control problem with our terminal emulation
packages that access our VAX cluster using an IP link (known as the PSU
Backbone here at Penn State).  The two software packages we are using are
NCSA Telnet 2.2 and Brown University's TN3270 (which does IBM emulation).
Both packages are using VERY similiar config.tel files.  What happens is
that during the scrolling of l;ong documents, the flow control is being
turned off, but not being turned back on.  The VAX still thinks I'm
connected, and I can even continue and logoff.  But my screen doesn't
change (obviously).  Somewhere along the line, the flow control ON is
not being interpretted.

I've eliminated the AppleTalk network as the problem.  I had my MAC and
the Kinetic's FastPath taken off the network.  The same problem occurred.
I've also had the same problem on other AppleTalk networks that are not
connected to our LAN.  So I don't believe our AppleTalk network is the
sole problem.

As far as I can tell, the problem is with the software's config.tel
file, the Kinetics FastPath configuration (K-Star), the settings on the
VAX (CMU Tektronix software), or our Backbone (doubtful).

Any help, simple or complex is greatly needed.
