- Selected ANSI (VT100) ESCape codes
- ----------------------------------
- by Rob Elliott
- Illini Data Fido 115/100
-
- These are ESCape codes that will be of most use to people designing VT100
- graphics displays. Not all of the codes are listed, just the most useful
- ones.
-
-
- What it does The code
- ------------ ESC = 27d --------
- Cursor up Pn lines `--------> ESC[PnA
- Cursor down Pn lines ESC[PnB
- Cursor forward (right) Pn lines ESC[PnC
- Cursor backward (left) Pn lines ESC[PnD
- Cursor sent to line Pl and column Pc ESC[Pl;PcH or
- ESC[Pl;Pcf
- Cursor position saved ESC7
- Cursor position restored ESC8
-
- Change current line to double-height Top half ESC#3
- Change current line to double-height Bottom half ESC#4
- Change current line to normal size ESC#5
- Change current line to double-width ESC#6
-
- Character Attributes ESC[Ps;Ps;Ps;...Psm
-
- Ps = 0 or none All attributes off
- 1 Bold on
- 2 Underscore on
- 5 Blink on
- 7 Reverse video on
-
- Erase from cursor to end of line ESC[K
- Erase from cursor to end of screen ESC[J
- Erase from beginning of line to cursor ESC[1K
- Erase from beginning of screen to cursor ESC[1J
- Erase entire line containing cursor ESC[2K
- Erase entire screen ESC[2J
-
- United Kingdom Character Set ESC(A
- United States (ASCII) Character Set ESC(B
- Special graphics set (line drawing set) ESC(0
-
- Set scrolling from top Pt to bottom Pb ESC[Pt;Pb
- Set VT52 mode ESC[?2l
- Set 132 column mode ESC[?3h
- Set 80 column mode ESC[?3l
- Set smooth scroll ESC[?4h
- Set jump scroll ESC[?4l
- Set reverse screen (light background) ESC[?5h
- Set normal screen (dark background) ESC[?5l
-
-
- Line Drawing Character Set
- --------------------------
- When the line drawing set is entered, via ESC(0,
-
- -This- -will show-
- \ Diamond
- a Checkerboard
- e Degree sign
- g Plus/minus sign
- j Lower-right box corner
- k Upper-right box corner
- l Upper-left box corner
- m Lower-left box corner
- n Intersecting lines
- o Horizontal line - Scan 1 (bottommost)
- p Horizontal line - Scan 3
- q Horizontal line - Scan 5 (use this to match box corners)
- r Horizontal line - Scan 7
- s Horizontal line - Scan 9 (topmost)
- t Left "T"
- u Right "T"
- v Top "T" (looks normal)
- w Bottom "T" (upside down)
- x Vertical bar
- y Less than or equal to sign
- z Greater than or equal to sign
- | Not equal to
- ( Pi sign
- ) UK pound sign
- ~ Centered dot
-
- Window: Line Sloping up: A normal box:
- lqwql
- x x x lqqqqqqqqk
- tqnqu opqrs x x
- x x x mqqqqqqqqj
- mqvqj
-
-
- Notes
- -----
- I highly recommend including the following sequence at the beginning of each
- ANSI file:
-
- ESC[?2lESC<
-
- This makes the computer jump in and out of VT52 mode. This resets all the
- character sets to G0 designator (especially important) and everything else.
- Using this will make sure the character sets show up only when they are
- supposed to (no graphics characters when it's a text screen and vice versa).
-
-
- On IBMs
- -------
- There are several ways to view these on an IBM PC. To have ANSI codes work
- locally (just TYPE the files and the displays appear) you can do several
- things.
-
- 1. Assign ANSI.SYS (free with PC-DOS) as a device driver. Do this by putting
- this line in CONFIG.SYS:
-
- DEVICE=ANSI.SYS
-
- 2. Download Fansi-Console (FCONSOLE) from any BBS that has it available,
- and install that as specified in the instructions.
-
- To view the codes remotely, it's best to get a VT100 emulating terminal
- program. Many commercial programs have this option. PC-VT, in the public
- domain, was written explicitly for this emulation. CrossTalk XVI, SmartCom II,
- and PTel are some commercial programs with this support.
-
-
- So...

- Send any questions or comments to Illini Data Fido 115/110.
- If you call direct, make sure you're using a VT100 emulator!
