If you compile xterm with '--enable-rectangles', it'll understand
some extra commands:
DECCRA Copy rectangular area
\e[ Pts;Pls;Pbs;Prs;Pps;Ptd;Pld;Ppd $v
DECERA Erase rectangular area
\e[ Pt;Pl;Pb;Pr $z
DECFRA Fill rectangular area
\e[ Pch;Pt;Pl;Pb;Pr $x
DECSERA Selective erase rectangular area
\e[ Pt;Pl;Pb;Pr ${
DECCARA Change attributes in rectangular area
\e[ Pt;Pl;Pb;Pr;Ps1;...Psn $r
DECRARA Reverse attributes in rectangular area
\e[ Pt;Pl;Pb;Pr;Ps1;...Psn $t
DECSACE Select attribute change extent
\e[ Ps *x
Cheers,
Michael.
