Help needed with Sun 2 IBM communication program

[STRIANTAFYLL%34985.gm at hac2arpa.hac.com]

Hello Sun Users,

I have a question related to Sunlink / DNI programming interface.  Sunlink
DNI of course allows access to a (Heaven Forbid) IBM mainframe. I am
trying to get a program to talk to the mainframe using the DAILIB library
that Sun provides, plus something based on their example code (both under
/usr/sunlink/dai).

The program pretty much lets you open up a session to the mainframe, then
send commands, and search for responses. All works ok execpt when the
mainframe (running MVS/TSO) goes into full screen mode (i.e. as in when
you specify log on parameters or deal with any kind of ISPF or DMS panel
(the MVS equivalent of X-windows :-))

So my question is, oh net, has anyone figured this out? we tried
specifying coordinates for the text but the thing won't recognize our
input at all; we keep getting screen errors from the MVS side.  Do we need
to specify some kind of special mode to talk to a full screen application?

Your help will be appreciated, and possibly your sympathy as well :-)
Environment is Sun386i's and Sun 4/280's running SunOS 4.0.2...
