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!. --- Bob Bridges, [email protected], cell 336 382-7313 /* Confession without repentance is just bragging. -Rev Eugene Bolton */ -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Seymour J Metz Sent: Monday, August 24, 2020 18:00 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. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Seymour J Metz Sent: Monday, August 24, 2020 17:54 Is it politically correct to use a VTAM packet trace? -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Clifford McNeill Sent: Monday, August 24, 2020 13:39 If a VTAM session monitor is between the PC and TSO, it could have PF21 assigned to some purpose and not passing it on. ________________________________________ From: IBM Mainframe Discussion List <[email protected]> on behalf of Bob Bridges <[email protected]> Sent: Monday, August 24, 2020 1:21 PM 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. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Paul Gilmartin Sent: Monday, August 24, 2020 13:08 Can you sniff the data stream on both the PC and the z? Is the behavior different with a different emulator or PC? --- On Mon, 24 Aug 2020 12:57:57 -0400, Bob Bridges wrote: >This is a really weird one.

If the keystroke is being sent by my PC, and the 3270 emulation is converting it to <PF21>, why does ISPF not respond to it? Any ideas out there? I'll take anything, at this point, no matter how unlikely. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
