Title: Maxess 1.2.1 and Machine Check Error Code 838
date: 8/15/89

Copyright 3Com Corporation, 1991.  All rights reserved.

Under Maxess version 1.2.1, when a 3270 command is embedded
within a Write structured field, a message similar to the
following will appear on the 3270 screen:

              mchk_end code 838 SF3270DSC line 110

The error indicates a structured field 3270 data stream conflict,
in this case at line 110.

It appears because Maxess 1.2.1 does not support the 3270DS
structured field.  To work around the problem, set the terminal
definition to 3277 on the host side.

This error is often seen when using an AS400 as the host, and
configuring the terminal definition for 3278/9.

Note:  Maxess version 1.3.0 does support 3270DS structured
fields.
