What terminal uses ESC[s and ESC[u?  The BBN Software Products Escape Sequence
Cross Index lists them as setting left and right margins (LN03 and VT420)
and setting tab stops (LN03) and various programmable strings like the
programmable keys, answerback messages, and latent expression (HDS GVT).
Nothing is mentioned re: their functionality on the VT220.

The general ANSI sequence for save/restore cursor is ESC#7 and ESC#8
respectively.  They don't work on some printers and on some of the SUN
consoles (and, of course, non-DEC-compatible terminals).
