Sven asked about this on an internal IBM discussion channel and I
mentioned that there are two issues that I can see in the Linux 3270
support:
1. Linux is definitely doing it wrong on z/VM. Linux infers the
dimensions of the screen from a model number. (Bzzzzzzt!) If you
have a standard-size screen for model 2, 3, 4, or 5, then the model
number from DIAG 0x210 will be correct. Otherwise it will reflect
model 2. I'm not sure why CP does that or why Linux is using the
model number at all. Even at the turn of the century it was
irrelevant.
2. Linux doesn't detect a reconnect event, so it doesn't know to
re-query the device and adjust any 'views' that have been created.
To be honest while someone could invest time in here, I think the
proper solution for Linux would be to improve z/VMs ASCII console
support (e.g. make it virtual instead of attaching the LPAR one and
provide a console server).
"second"
I'd really like to see that. It's 2023 already. Just sayin.
