JHHL,

I looked at our 5250 code, and it looks like we send a negative response (1005, 01, 05) when we get this structured field, reporting it invalid. So, that probably doesn't help you much :-)

Like Justin said, I would suggest setting up Wireshark and having your customer run this using IBM i Access or Access Client Solutions and see what it does. Then, compare to the info found in the 5494 functions reference manual.

I'm guessing this doesn't come up very often!

Hmm. I've never used any of the tools you describe, but I have several
built-in data stream dump tools built into our emulator, and I've told
the customer where to find them (they're in a hidden menu), and asked
for a buffer dump (and a trace, if they figure out a way to make it
happen predictably). But that's only going to tell me more about what IS
happening, not what SHOULD BE happening.

Seems to me that the ideal situation would be to have some way of
getting a data stream dump with the application in question talking to a
real terminal.

What really bugs me is that (1) according to the 5494 manual, the "WSF:
Query Station State" is malformed, (2) it's being sent even though our
emulator's response to "WSF: Query" explicitly says that neither it nor
"WSSF: WSC Customization" are supported, and (3) while I can find a DSM
API for sending "WSF: Query," I can't find ANYTHING short of a UDDS that
will send a "WSF: Query Station State" or a "WSSF: WSC Customization."
