3270 Applet May Hang If Session Uses Definite Response Only

• Microsoft SNA Server, versions 2.0, 2.1, 2.11, 2.11 SP1
  on the following platforms: NT

SYMPTOMS

The 3270 applet that is included with SNA Server may send a message using the Exception Response protocol even though only the Definite Response protocol has been negotiated during the bind. Therefore, the 3270 emulator stops responding (hangs) unexpectedly.

CAUSE

The 3270 applet does not check the session parameter all the time to determine what type of request it should send.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 2.11 and 2.11 Service Pack 1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
