.This is a 3270 datastream. If you displayed it in hex, you would see a series
of SBA, address and data. This tells us a few things:
1. CONMODE 3270 uses DIAG 58 to handle data as a 3270 datastream versus CONMODE
3215 treats the 3270 stream as simple data.
2. Seymour was wrong that the SECUSER could not handle a 3270 screen. Like a
real 3270, CONMODE 3215 receives changes to the screen instead of a complete
screen refresh each time.
3. Most important, it shows z/OS dropped 3215 printer console support and
forces 3270 full screen.
UNIT(PRT) on the console definition would be simple to test but I don't think
it will work. I suspect it will still use 3270 datastream. Even if it is a 3270
datastream, you could write prop execs to convert from datastream to lines.
Fullscreen scrolls on the screen so PRT eliminates the dumplicated lines
problem.
More likely to work is to find a 3211, 3203-5 or 1403 definition in the z/OS
HCD and specify UNIT(PRT) DEVICE(###) where ### is the printers address. I
doubt it behaves like a 3270 datastream so it's possible it will work but no
guarantees.
If you are forced to use V CN(*),ACT then you will need to lower your
expectations. I will repeat that this has nothing to do with the VM z/OS user
"console" statement. Comment it and issue the command. You will find it still
works. Think about a real z16 hardware console in the computer room. Rarely
will someone use this hardware console but on rare occasions you may need
access to the hardware and z/OS consoles at the same time. You never want z/OS
consoled active in the hardware unless someone is actively using it. IBM does
not allow you to automatically activate this z/OS console in the hardware
console. Instead, you must ACTIVATE it when you need it and then DEACTIVATE it
when you are finished.
The word CONSOLE in z/VM is misleading and has a different interpretation for
z/OS, z/VSE, hardware and more. For z/VM, "CONSOLE" is a statement in each user
definition in the user directory. It has nothing to do with consoles. It
defines a virtual device that sends to and receives from the logon terminal.
The word "console" pushes z/OS and z/VSE sysprogs to use a z/OS or z/VSE
console. If the z/OS sysprog chose a device address defined to VTAM instead of
a console, the VTAM logon screen would appear instead of a z/OS console
terminal. There is nothing that makes a terminal uniquely a console other than
a z/OS defined a device address as a console.
Console has a real meaning to z/OS, z/VSE and hardware. E.g. every IBM z
computer has a hardware console to define LPARs and IPL systems.

Note that these lines aren't 80, or 132, or anything like that.
TERMINAL LINESIZE is 00. Tried 132; all that seems to do is cut off lines.
What I see via SECUSER is also different from what I see in the SPOOLed
console: there are a lot more blank lines displayed via SECUSER, and more
linewraps. Guessing that's because there's some 3270 datastream stuff that's
semi-getting handled, but can't prove that. It's sure not in the SPOOLed
console, not even as undisplayables.
So...progress, I guess? I can now IPL via XAUTOLOG and watch it, if a bit
incoherently.
