We ran afoul of one other gotcha: Run a VTAM trace on the failing session.
Look at the query reply, and make sure it isn't lying about its capabilities.
If not, then your host program may be making invalid assumptions about the
terminal's capabilities, and acting as though some unspecified capability
is there when it wasn't mentioned in the query reply, just because none of
the standard terminals acts that way.

Case in point: FTP Software's PC/TCP sends query replies saying only that
it supports extended highlighting and colors, and no other extended datastream
functions. PHOENIX 7.1.1 got that reply and assumed (incorrectly) that the
device supported the 3270DS WSF, as well...and things broke. (This is fixed
in PHOENIX 7.2, BTW.) If your application makes invalid assumptions, complain
at your vendor.
