This document explains the how the ANSI escape sequences are
|
|||
|
defined for the IBM PC.
|
|||
|
|
|||
|
Notes:
|
|||
|
|
|||
|
1. The default value is used when no explicit value is given
|
|||
|
or a value of zero is given.
|
|||
|
|
|||
|
2. Pn - Numeric parameter. A decimal number specified
|
|||
|
with ASCII digits.
|
|||
|
|
|||
|
3. Ps - Selective parameter. Any decimal number that is
|
|||
|
is used to select a subfunction. Multiple subfunctions
|
|||
|
may be selected by separating the parameters with
|
|||
|
semi-colons.

CUP - Cursor Postion
|
|||
|
|
|||
|
ESC [ Pl ; Pc H
|
|||
|
|
|||
|
HVP - Horizontal & Vertical Postion
|
|||
|
|
|||
|
ESC [ Pl ; Pc f
|
|||
|
|
|||
|
CUP and HVP move the cursor to the position specified by
|
|||
|
the parameters. The first parameter specifies the line number
|
|||
|
and the second parameter specifies the column number. The
|
|||
|
default value is one. When no parameters are given the cursor
|
|||
|
is moved to the home postion.
|
|||
|
|
|||
|
CUU - Cursor Up
|
|||
|
|
|||
|
ESC [ Pn A
|
|||
|
|
|||
|
Moves the cursor up one line without changing columns. The
|
|||
|
value of Pn determines the number of lines moved. The default
|
|||
|
value for Pn is one. This sequence is ignored if the cursor
|
|||
|
is already on the top line.
|
|||
|
|
|||
|
CUD - Cursor Down
|
|||
|
|
|||
|
ESC [ Pn B
|
|||
|
|
|||
|
Moves the cursor down one line without changing columns.
|
|||
|
The value of Pn determines the number of lines moved. The
|
|||
|
default value for Pn is one. This sequence is ignored if the
|
|||
|
cursor is already on the bottom line.
|
|||
|
|
|||
|
CUF - Cursor Forward
|
|||
|
|
|||
|
ESC [ Pn C
|
|||
|
|
|||
|
Moves the cursor forword one column without changing lines.
|
|||
|
The value of Pn determines the number of columns moved. The
|
|||
|
default value for Pn is one. This sequence is ignored if the
|
|||
|
cursor is already in the rightmost column.
|
|||
|
|
|||
|
ESC [ Pn D
|
|||
|
|
|||
|
Moves the cursor back one column without changing lines. The
|
|||
|
value of Pn determines the number of columns moved. The default
|
|||
|
value for Pn is one. This sequence is ignored if the cursor
|
|||
|
is already in the leftmost column.
|
|||
|
|
|||
|
DSR - Device Status Report
|
|||
|
|
|||
|
ESC [ 6 n
|
|||
|
|
|||
|
The console driver will output a CPR sequence on receipt of
|
|||
|
DSR.
|
|||
|
|
|||
|
CPR - Cursor Position Report (from console driver to system)
|
|||
|
|
|||
|
ESC [ Pn ; Pn R
|
|||
|
|
|||
|
The CPR sequence reports current cursor position via
|
|||
|
standard input. The first parameter specifies the current
|
|||
|
line and the second parameter specifies the current column.
|
|||
|
|
|||
|
SCP - Save Cursor Postion
|
|||
|
|
|||
|
ESC [ s
|
|||
|
|
|||
|
The current cursor position is saved. This cursor position
|
|||
|
can be restored with the RCP sequence.
|
|||
|
|
|||
|
RCP - Restore cursor position
|
|||
|
|
|||
|
ESC [ u
|
|||
|
|
|||
|
Restores the cursor position to the value it had when the
|
|||
|
console driver received the SCP sequence.

ED - Erase Display
|

|
|||
|
position.

|
|||
|
EL - Erase Line
|
|||
|
|
|||
|
ESC [ K
|
|||
|
|
|||
|
Erases from the cursor to the end of the line and includes
|
|||
|
the cursor position.

SGR - Set Graphics Rendition
|
|||
|
|
|||
|
ESC [ Ps ; ... ; Ps m
|
|||
|
|
|||
|
Invokes the graphic rendition specified by the parameter(s).
|

|

|
|||
|
parameter(s) until the next occurence of SGR.

K E Y B O A R D R E - A S S I G N M E N T
|
|||
|
|
|||
|
Although not part of the ANSI 3.64-1979 or ISO 6429 standard
|
|||
|
the IBM PC keyboard re-assignment was done in a compatible
|
|||
|
way.
|
|||
|
|
|||
|
The control sequence is:
|
|||
|
|
|||
|
ESC [ Pn ; Pn ; ... Pn p
|
|||
|
or ESC [ "string" ; p
|
|||
|
or ESC [ Pn ; "string" ; Pn ; Pn ; "string" ; Pn p
|
|||
|
or any other combination of strings and decimal numbers
|
|||
|
|
|||
|
The final code in the control sequence ("p") is one reserved
|
|||
|
for private use the by ANSI 3.64-1979 standard.
|
|||
|
|
|||
|
The first ASCII code in the control sequence defines which
|
|||
|
code is being mapped. The remaining numbers define the
|
|||
|
sequence of ASCII codes generated when this key is
|
|||
|
intercepted.
|
|||
|
|
|||
|
To every rule there is an exception, however! If the first
|
|||
|
code in the sequence is zero (NUL) then the first and second
|
|||
|
code make up an extended ASCII re-definition.
|
|||
|
|
|||
|
Here are some examples:
|
|||
|
|
|||
|
1. Reassign the Q and q key to the A and a key (and the other
|
|||
|
way as well):
|
|||
|
|
|||
|
ESC [ 6 5 ; 8 1 p A becomes Q
|
|||
|
ESC [ 9 7 ; 1 1 3 p a becomes q
|
|||
|
ESC [ 8 1 ; 6 5 p Q becomes A
|
|||
|
ESC [ 1 1 3 ; 9 7 p q becomes a
|
|||
|
|
|||
|
2. Reassign the F10 key to to a dir command followed by a
|
|||
|
carriage return:
|
|||
|
|
|||
|
ESC [ 0 ; 6 8 ; " d i r " ; 1 3 p
|
|||
|
|
|||
|
The 0;68 is the extended ASCII code for the F10 key. 13
|
|||
|
decimal is a carriage return
|
|||
