ESC[row;column x Cursor Positioning to the Status Line
The sequence ESC[row;column x will cause the cursor to move
to the status line (line 25 of the screen). The value for "row"
is ignored. The value for "column" is a decimal whole number
between 1 and 80 or 1 and 132, depending on the columns option
(refer to Section 5). The column value defaults to 1 if omitted
or O. If the column value is larger than the line length (80 or
132), the column position is defaulted to the maximum value.
User Defined Scrolling Region
ESC[top row;bottom row r Split Screen
Receiving the escape sequence ESC[top row;bottom row r will
cause the screen to be configured into two static regions and
one scrolling region, one static region and one scrolling re-
gion, or one scrolling region. Whenever the split screen escape
sequence is received, the cursor is homed. The cursor can be
freely moved between screen regions with cursor addressing when
not in the Origin mode (refer to escape sequences ESC[?6h/
ESC[?61
of this section) but destructive scrolling will occur
only in the scrolling region. If in Origin mode, the cursor
cannot be moved outside the scrolling region with the exception
of the status line. The scrolling region must have at least two
lines. Refer to Section "6. Destructive Scrolling and Scrolling
Regions." Missing parameters or 0 will default to 1 for the top
row and 24 for the bottom row.
