CUrsor Positionina Escape Sequences
The following escape sequences provide for cursor posi-
tioning to a specific row and column. If no parameter numbers
are defined, a 1 is assumed and the cursor will go to row or
column 1. "Absolute" is in reference to the entire screen.
ESC[6n Cursor Position Report Request
Receiving the sequence ESC[6n causes the terminal to re-
spond with the cursor position sequence ESC[row;column R. The
row and column
values are the same as those which are used to
address the cursor position with Origin mode (refer to escape
sequences ESC[?6h/ESC[?6I) off, i.e., cursor position is rela-
tive to the first row (line) and first column of the display.
ESC[row;column H Cursor Addressing
User"'s Guic1e
August: 1985
Cursor addressing positions the cursor with the address
scheme ESC[row;column H or ESC [row; column f. The values for row
and column
are the values for the line number and column number
at which the cursor is to be positioned. The row value ranges
from 1 to 24 and the column value ranges between 1 and 80 or
132, depending on the columns option (refer to Section 5). If
the values are missing or 0, they default to 1. If the row
value is larger than 24, then the value is defaulted to 24; if
the columns value is larger than the line length (80 or 132),
the value is defaulted to the maximum value.
If in the Origin mode (refer to escape sequences ESC[?6h/
ESC[?6I), cursor addressing is relative to the home position of
the-sc~oHing regIon. The cursor cannot be moved outside of the
scrolling region with the exception of the status line.
