You have put the screen into `roll mode'.  Suns have a `roll mode'
and a `scroll mode'.  The sequence  ESC [ r  enters roll mode; the
sequence  ESC [ <n> s  enters scroll mode with the scroll line count
set to <n> (default 1).

It is perhaps unfortunate that the VT100's scrolling region command
uses the  ESC [ r  sequence.  This invariably confuses someone here
at least once a year.  (But it would not happen if people did not
keep claiming that their Suns are VT100s.  Not a good trade, if
you ask me :-) .)
