Yes ... (Thanks)

So far, based on your comments, the code and the reference manual I've found a
number of problems related to the confusion about bit numbering and also
related to the display of "value names" for certain bit-fields.

I think I'll need to do a complete review of the field definitions and of the
code.


Re:

 "I'm a bit hesitant to open this bug, because it seems unlikely this would
have
  gone unnoticed so long; but I've triple-checked the IBM docs and it really
  appears the tn3270 sub-dissector is wrong."

It would seem that maybe this dissector isn't used much... !

Just for my curiosity, is TN3270 still used much in the wild ?
What is your need for Wireshark TN3270 dissection ?
(Were you using Wireshark to diagnose a TN3270 issue ?)

(Oh: Microfocus...  Cobol...  Rumba... ....)
