Though I have worked with real 3270's in the past, I am no expert on the
CUT or DFT protocols.  However, it would not surprise me at all if, for
a 3278, that information is provided by the controller -- but not as
part of the data stream that the host computer sees.

I found these documents, but they don't address that status line,
because they are for the older 3271/3272 controllers.
