1B是ESC的十六进制
- ANSI Escape Sequences
- What ANSI escape sequences can be used?
- ANSI escape sequences provide cursor and screen control in OS/2 character
- mode sessions. By default ANSI support is turned ON (although it may be
- turned off with the command ANSI OFF). ANSI support is also available in
- DOS sessions if the device driver ANSI.SYS is loaded. See the online
- Command Reference for details.
- The following ANSI escape sequences are available:
- Key
- ESC Refers to ASCII code 27 (i.e. the Escape key)
- # Replace with the appropriate number
- .... Replace with additional attributes, if desired
-
- Escape Code Sequence Function
- Cursor Controls
- ESC[#;#H or ESC[#;#f Moves cursor to line #, column #
- ESC[#A Moves cursor up # lines
- ESC[#B Moves cursor down # lines
- ESC[#C Moves cursor forward # spaces
- ESC[#D Moves cursor back # spaces
- ESC[#;#R Reports current cursor line and column
- ESC[s Saves cursor position for recall later
- ESC[u Return to saved cursor position
- Erase Functions
- ESC[2J Clear screen and home cursor
- ESC[K Clear to end of line
- Set Graphics Rendition
- ESC[#;#;....;#m Set display attributes where # is
- 0 for normal display
- 1 bold on
- 4 underline (mono only)
- 5 blink on
- 7 reverse video on
- 8 nondisplayed (invisible)
- 30 black foreground
- 31 red foreground
- 32 green foreground
- 33 yellow foreground
- 34 blue foreground
- 35 magenta foreground
- 36 cyan foreground
- 37 white foreground
- 40 black background
- 41 red background
- 42 green background
- 43 yellow background
- 44 blue background
- 45 magenta background
- 46 cyan background
- 47 white background
- ESC[=#;7h Put screen in indicated mode where # is
- 0 for 40x25 black and white
- 1 40x25 color
- 2 80x25 black and white
- 3 80x25 color
- 4 320x200 color graphics
- 5 320x200 black and white graphics
- 6 640x200 black and white graphics
- 7 to wrap at end of line
- ESC[=#;7l Resets mode # set with above command
- Keyboard Reassignments
- ESC[#;#;....#p The first ASCII code defines what is to be
- changed; the remaining codes define what it
- is to be changed to; strings are permitted.
-
- Examples:
- ESC[65;81p - A becomes Q
- ESC[81;65p - Q becomes A
- ESC[0;68;"dir";13p - Assign the F10 key to
- a DIR command.
- The 0;68 portion is the extended ASCII code
- for the F10 key and 13 is the ASCII code
- for a carriage return.
- Other function key codes: F1=59, F2=60,
- F3=61, ... F10=68.
-
- You can use ANSI escape sequences in the PROMPT environment variable to
- create complex command line prompts. See the online Command Reference
- (under PROMPT) for details.
- For example, if you have a color monitor, try editing your CONFIG.SYS
- file so that
- SET PROMPT=$e[32;40m$e[1m[$P]$e[0m
-
- to obtain a more colorful OS/2 command line prompt. (Case is significant
- in the example given.) You can do the same for your DOS sessions if you
- edit PROMPT in AUTOEXEC.BAT, assuming you have ANSI.SYS loaded. Note
- that the $i portion of your PROMPT will enable the help line at the top
- of the window or screen. It is not included in the example above.
