Q161191: TN3270 Client Cannot Get Past the USSTAB Screen Using ENTER

Article: Q161191
Product(s): Microsoft SNA Server
Version(s): WINDOWS:2.0,2.1,2.11,2.11 SP1
Operating System(s): 
Keyword(s): kbnetwork

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft SNA Server, versions 2.0, 2.1, 2.11, 2.11 SP1 
-------------------------------------------------------------------------------


SYMPTOMS
========

TN3270 clients cannot proceed past the USSTAB screen (also known as a msg- 10
screen) by pressing the ENTER key. In this configuration, the clients receive
the USSTAB screen from the host when the notify is sent. At the site where this
problem was raised, the USSTAB screen prompted the user to press ENTER to
continue. It actually accepts any keystroke, but has been written to prompt for
ENTER.

CAUSE
=====

The TN3270 server receives the ENTER keystroke from the client (AID key x'7D'),
but sends the host a frame with no data (a frame with a TH, RH, but no RU).
