Re: 5250 data stream gurus: anybody know anything about "Write Structured Field: Query Station State"?

I'm not a 5250 internal guy whatsoever. However, if you want to get a
better idea whats going on, could you walk the customer through getting
pcap file of their TN5250 session traffic? Maybe seeing the whole thing
might get you some insight

If its a windows client you have wireshark and tcpdump, which both require
the winpcap service installed, but there is a command line utility that
doesn't require that called rawcap. http://www.netresec.com/?page=RawCap

Once you have the capture stream, I'm sure you guys got tools to look at
it, but maybe looking it the session in wireshark might give you some
insight? https://wiki.wireshark.org/TN5250. Maybe that dissector might know
something about the sequence that you don't. Also, whoever wrote
that dissector might be a person you can contact for advice.

I just got a report that a customer using our terminal emulator is
getting a "d9 72 40 00 FF EF" in the data stream, which the 5494
Functions Reference defines as "Write Structured Field: Query Station
State," and it goes on to say something about workstation customizations.

I've never encountered this before, don't know how to respond to it, and
don't even know how to rig something to send it (short of building it as
a user-defined data stream, which could take quite some time).

Can anybody offer insights?
