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.
|
||||
|
||||
This device driver must be loaded by a < DEVICE > or < DEVICEHIGH > command in
|
||||
your CONFIG.SYS file.
|
||||
|
||||
Note: In this topic bold letters in syntax and ANSI escape sequences
|
||||
indicate text you must type exactly as it appears.
|
||||
|
||||
Syntax
|
||||
|
||||
DEVICE=[drive:][path]ANSI.SYS [/X] [/K] [/R]
|
||||
|
||||
Parameter
|
||||
|
||||
[drive:][path]
|
||||
Specifies the location of the ANSI.SYS file.
|
||||
|
||||
Switches
|
||||
|
||||
/X
|
||||
Remaps extended keys independently on 101-key keyboards.
|
||||
|
||||
/K
|
||||
Causes ANSI.SYS to treat a 101-key keyboard like an 84-key
|
||||
keyboard. This is equivalent to the command SWITCHES=/K.
|
||||
If you usually use the SWITCHES=/K command, you will need
|
||||
to use the /K switch with ANSI.SYS.
|
||||
|
||||
/R
|
||||
Adjusts line scrolling to improve readability when ANSI.SYS
|
||||
is used with screen-reading programs (which make computers
|
||||
more accessible to people with disabilities).
|
||||
|
||||
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<6F><6E>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.
|
||||
|
||||

|
||||
19 320 x 148 x 200 color (256-color graphics)
|
||||
|
||||
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.
