TN3270 Server Does Not Handle Models 3, 4, and 5 Correctly (160979)
The information in this article applies to:
- Microsoft SNA Server 2.0
- Microsoft SNA Server 2.1
- Microsoft SNA Server 2.11
- Microsoft SNA Server 2.11 SP1
This article was previously published under Q160979 SYMPTOMS
Various terminal types are supported by the TN3270/e Service. However, if
the emulator requests a 3270 model 3, 4, or 5, the screen may appear to be
truncated or missing characters.
CAUSE
The TN3270 Server does not format SSCP data correctly for models 3, 4, and
5; it has the following three problems:
- For models 3, 4, and 5 the TN3270 Server should never send the ERASE-
WRITE command. Instead, it should send the ERASE-WRITE-ALTERNATE
command.
- The TN3270 Server has an array containing the 3270 screen addresses.
Unfortunately, this array is not large enough for model 3 and model 4
screens.
- There should be a different array for model 5 screens.
RESOLUTION
The TN3270 Server's handling of models 3, 4, and 5 was incorrect. The
TN3270 Server now formats these screens correctly. To resolve this problem,
obtain the hotfix mentioned below.
STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.0,
2.1, 2.11, and 2.11 Service Pack 1.
This problem was corrected in the latest Microsoft SNA Server 2.11 U.S.
Service Pack. For information on obtaining the service pack, query on the
