Good point!  I came into mainframe security from the development side and
have never been a systems programmer, so terms like "VTAM" are mostly a
mystery to me.  But once I'm connected to my client's VPN, and looking at
the Win-10 desktop at end, I open the mainframe app and log on directly to
TSO, bypassing SuperSession.

Still, as you no doubt saw by the time you got through the rest of the
emails in this thread, <Shift-F9> is getting no response not only in 3270
emulation but also in Outlook on the client's side.  So I think it's safe to
conclude the problem is happening before the keystroke gets to Attachmate
Extra!.

The problem is not in TSO or ISPF. The problem is your keyboard mapping if
your logging on directly to TSO. If you're logging on via, e.g., TPX, check
what keys it's intercepting.

Is it politically correct to use a VTAM packet trace?

If a VTAM session monitor is between the PC and TSO, it could have PF21
assigned to some purpose and not passing it on.

I have to plead, in response to both questions, not so much inability and
ignorance.  I once saw a vendor apply a packet sniffer to a problem we had
at another client, when we couldn't figure out why a connection wasn't being
accepted.  He was able to show us that the client and server couldn't find a
common encryption scheme.  I immediately saw the value of packet sniffers,
and the next time I had a problem on my own machine I got myself a copy of
I-think-it-was-WireShark.  But I couldn't figure out how to make it work.
That was about a year ago, and it's as close as I ever got to sniffing
throughput.  Sounds like a great idea, but I don't know how.  And I'm
working remote, of course, so I couldn't do it on the big box in any case.

I understand the other question, but my ignorance isn't much less in that
area.  I've worked with many clients, and have long suspected that I can use
any 3270 emulation client with box once the connection is made.  But so far
I haven't tested that notion.  And in this case the emulation client
(Attachmate Extra!) is provided from the other end after I connect to their
network, so I guess I wouldn't be able to in any case.

Can you sniff the data stream on both the PC and the z?

Is the behavior different with a different emulator or PC?
