It's my impression that SUPDUP (as described in Richard Stallman's
1983 AI Lab Memo 644; I don't have the RFC's handy) doesn't support
alteration of display terminal characteristics after the connection
initialization takes place. Wouldn't that rule out its use in a
modern windowing environment? Windows can be resized.

It looks like a very nice job, just the same. I have a generic
Unix implementation here; are there any implementations of the
graphics extension available for SunView or X Windows?
