<TITLE>ANSI.SYS -- ansi terminal emulation escape sequences</TITLE> |
|
|
|
|
|
ANSI.SYS |
|
|
|
|
|
Defines functions that change display graphics, control cursor movement, and |
|
|
reassign keys. The ANSI.SYS device driver supports ANSI terminal emulation |
|
|
of escape sequences to control your system's screen and keyboard. An ANSI |
|
|
escape sequence is a sequence of ASCII characters, the first two of which |
|
|
are the escape character (1Bh) and the left-bracket character (5Bh). The |
|
|
character or characters following the escape and left-bracket characters |
|
|
specify an alphanumeric code that controls a keyboard or display function. |
|
|
ANSI escape sequences distinguish between uppercase and lowercase letters; |
|
|
for example,"A" and "a" have completely different meanings. |
|
|
|
|
|
|
|
|
Parameters used in ANSI escape sequences |
|
|
|
|
|
Pn |
|
|
Numeric parameter. Specifies a decimal number. |
|
|
|
|
|
Ps |
|
|
Selective parameter. Specifies a decimal number that you use to select |
|
|
a function. You can specify more than one function by separating the |
|
|
parameters with semicolons. |
|
|
|
|
|
PL |
|
|
Line parameter. Specifies a decimal number that represents one of the |
|
|
lines on your display or on another device. |
|
|
|
|
|
Pc |
|
|
Column parameter. Specifies a decimal number that represents one of the |
|
|
columns on your screen or on another device. |
|

|
|
ANSI escape sequences for cursor movement, graphics, and keyboard settings |
|
|
|
|
|
In the following list of ANSI escape sequences, the abbreviation ESC |
|
|
represents the ASCII escape character 27 (1Bh), which appears at the |
|
|
beginning of each escape sequence. |
|
|
|
|
|
ESC[PL;PcH |
|
|
Cursor Position: Moves the cursor to the specified position |
|
|
(coordinates). If you do not specify a position, the cursor moves to the |
|
|
home position - the upper-left corner of the screen (line 0, column |
|
|
0). This escape sequence works the same way as the following Cursor |
|
|
Position escape sequence. |
|
|
|
|
|
ESC[PL;Pcf |
|
|
Cursor Position: Works the same way as the preceding Cursor Position |
|
|
escape sequence. |
|
|
|
|
|
ESC[PnA |
|
|
Cursor Up: Moves the cursor up by the specified number of lines without |
|
|
changing columns. If the cursor is already on the top line, ANSI.SYS |
|
|
ignores this sequence. |
|
|
|
|
|
ESC[PnB |
|
|
Cursor Down: Moves the cursor down by the specified number of lines |
|
|
without changing columns. If the cursor is already on the bottom line, |
|
|
ANSI.SYS ignores this sequence. |
|
|
|
|
|
ESC[PnC |
|
|
Cursor Forward: Moves the cursor forward by the specified number of |
|
|
columns without changing lines. If the cursor is already in the |
|
|
rightmost column, ANSI.SYS ignores this sequence. |
|
|
|
|
|
ESC[PnD |
|
|
Cursor Backward: Moves the cursor back by the specified number of |
|
|
columns without changing lines. If the cursor is already in the leftmost |
|
|
column, ANSI.SYS ignores this sequence. |
|
|
|
|
|
ESC[s |
|
|
Save Cursor Position: Saves the current cursor position. You can move |
|
|
the cursor to the saved cursor position by using the Restore Cursor |
|
|
Position sequence. |
|
|
|
|
|
ESC[u |
|
|
Restore Cursor Position: Returns the cursor to the position stored |
|
|
by the Save Cursor Position sequence. |
|
|
|
|
|
ESC[2J |
|
|
Erase Display: Clears the screen and moves the cursor to the home |
|
|
position (line 0, column 0). |
|
|
|
|
|
ESC[K |
|
|
Erase Line: Clears all characters from the cursor position to the |
|
|
end of the line (including the character at the cursor position). |
|
|
|
|
|
ESC[Ps;...;Psm |
|
|
Set Graphics Mode: Calls the graphics functions specified by the |
|
|
following values. These specified functions remain active until the next |
|
|
occurrence of this escape sequence. Graphics mode changes the colors and |
|
|
attributes of text (such as bold and underline) displayed on the |
|
|
screen. |

|
|
|
|
|
ESC[=Psl |
|
|
Reset Mode: Resets the mode by using the same values that Set Mode |
|
|
uses, except for 7, which disables line wrapping. The last character |
|
|
in this escape sequence is a lowercase L. |
|
|
|
|
|
ESC[code;string;...p |
|
|
Set Keyboard Strings: Redefines a keyboard key to a specified string. |
|
|
The parameters for this escape sequence are defined as follows: |
|
|
|
|
|
Code is one or more of the values listed in the following table. |
|
|
These values represent keyboard keys and key combinations. When using |
|
|
these values in a command, you must type the semicolons shown in this |
|
|
table in addition to the semicolons required by the escape sequence. |
|
|
The codes in parentheses are not available on some keyboards. |
|
|
ANSI.SYS will not interpret the codes in parentheses for those |
|
|
keyboards unless you specify the /X switch in the DEVICE command for |
|
|
ANSI.SYS. |
|
|
|
|
|
String is either the ASCII code for a single character or a string |
|
|
contained in quotation marks. For example, both 65 and "A" can be |
|
|
used to represent an uppercase A. |
|
|
|
|
|
IMPORTANT: Some of the values in the following table are not valid for all |
|
|
computers. Check your computer's documentation for values that |
|
|
are different. |
