Thanks Thomas for your promptly response. Just a last question.

If rectangle operations aren't widely available, how come does ncurses
implement e.g. attron?
The only solution I can think of is to have a backup buffer for the console,
change attributes for the rectangle of interest leaving characters untouched
and then reprinting chars+attrs to the console. Am I right?

What I was trying to do is to change attrs of a rectangle with ESC sequences
only (without ncurses aid). I'm afraid that I'll have to remeber the
rectangle contents (e.g. in a string), change attr mode at first and then
rewrite the string.
