I was looking at the scrolling.  Had not noticed this before, but at some p=
oint
since the terminfo for cons25 was written, the corresponding code was modif=
ied
to accept the vt100 scrolling control (which by the way is not part of
ISO-6429).  The terminfo entry in ncurses uses the analogous SU/SD sequences
which are in ISO-6429.  Scrolling regions also aren't part of ISO-6429 - on=
e of
those odd things that you should be aware of.

(I don't have a copy of the older ANSI spec, but since it was withdrawn sev=
eral
years ago, there's no point in discussing which features from it might not =
be
part of ISL-6429).
