capabilities and
resources to which other computers may be connected so that they can share

You need to code the screensize parameter under 3270. So, edit the .WS file
with any text editing software and add the following.
[3270]
QueryReplyMode=Auto
HostCodeP
Check what gets updated when you change the screen size to one of the other

the registry. And there's only so many places that PCOMM stores configuration

When you find what's updated, note how it stores this set
