For what it's worth, literally decades ago I changed all my default logmodes to
D4x3290 and never looked back. It will fall back to 24x80 if there's an
issue, which works on all emulated 3270s. Granted, this was on z/VM, which had
native non-SNA 3720 support long before it ever had VCNA or
square brackets X'AD' and X'BD')

I forgot to mention that OSA-ICC is a TN3270 server that presents the
appearance of a local non-SNA controller, which means that there is no exchange
of BIND. What's in the LOGMODE that you're using?

ISPF display screen size is also affected by the 'Terminal Characteristics'
section at the bottom of the ISPF option 0 screen. See what you have set
there.

It depends.
FOR REAL 3270 DISPLAYS:
Except for the 3277 generation, each 3270 display has a primary size and a
secondary size. TSO normally uses the secondary size if it is 80 wide. ISPF has
settings to control what it does.
For some displays the sizes are fixed. Starting with the 3180, some
Simple answer: 3270 hardware function called "Read Partion Query" which
returns the screen size (plus lots of other info about what the specific
terminal can do, such as code pages). Some programs are capable of issuing
the RPQ command and parsing the complex RPQ response. Other programs are
