Known Errors

These are the known errors in our products, logged as reported with versions and platforms affected as well as corrections and work-arounds.

This list is largely historical, since it records all problems that have been reported throughout G&R history. Only the most recently reported problems still exist, unless you are using a very old copy of the product, in which case you should update the product to the most recent version.

E1256: Ggate, TN3270 to GCOS8 Start Field Extended failed

Product: Ggate
Platform: All
Status: Fixed in 6.6, fix available for 6.5
Last updated: 2013-03-01 10:05:34

Ggate/TN3270 connections to GCOS8 applications generally use ASCII, and
the support was for the GCOS8 applications using ASCII data stream to
handle the 3270 terminal. IBM's specification of support for ASCII data
stream states that all characters from the application must be ASCII
graphical characters. Things like buffer addresses (binary for 3270
terminals) have to be mapped as two characters if they are fall in the
control character area of ASCII (0x80 - 0x9F). ASCII data stream
restricts the functionality of the 3270 terminal. For example SFE
(Start field extended) is EBCDIC 0x29 and in ASCII this is 0x89 i.e. in
the control character zone. The IBM 3270 manual does not specify any
way of sending this as two graphical ASCII characters, it simply states
that SFE is not supported for ASCII data stream. This is historical,
and there is no reason today that Ggate/TN3270 should restrict the
GCOS8 application to ASCII data stream. The fix allows GCOS8
applications to send ASCII control characters unencoded and Ggate maps
them to EBCDIC one-to-one.

There is no work-around.
