'vi' is a text editor. More specifically, it is the One True

If terminal size can't be retrieved and $LINES/$COLUMNS are not set,

this option makes vi perform a last-ditch effort to find it:
|
|
vi positions cursor to 999,999 and asks terminal to report real
|
|
cursor position using "ESC [ 6 n" escape sequence, then reads stdin.

This is not clean but helps a lot on serial lines and such.
