Support SNA Server 3270 Applet Keyboard Type-Ahead

ID: Q165851

The information in this article applies to:

Microsoft SNA Server, version 3.0
on the following platforms: NT

SYMPTOMS

The SNA Server 3270 applet does not support keyboard type-ahead. This prevents a user from entering data while the 3270 session is in an inhibited state.

CAUSE

The SNA Server 3270 applet does not support keyboard type-ahead.

RESOLUTION

An update to SNA Server 3.0 is available to correct this problem in the Windows NT, Windows 95, and Windows 3.x 3270 applet. To resolve this problem, obtain the hotfix mentioned below.

The 3270 applet now supports type-ahead by default. Keys entered while input is inhibited are queued and then processed when the input inhibit flag is cleared. Up to 256 keys may be queued. The type-ahead queue is cleared without processing the keys if the user presses the RESET, SYSREQ, or ATTN keys. To disable the type-ahead capability, edit the Win.ini file in the Windows directory as follows:


   [SnaServerWin3270]
      typeahead=0

Setting typeahead=0 disables type-ahead support. If this entry is not configured, or if typeahead=1, then type-ahead is enabled.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
