[ANSI] Escape Sequences
Intro
ANSI Escape sequences are used to perform special operations on the terminal, such as changing the output color, making it bold, printing at a specified coordinate etc.
The sequences
Wherever you see ‘#’, that should be replaced by the appropriate number.
Cursor Controls:
ESC[#;#H or ESC[#;#f (Moves cusor 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 & 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

- 04 underline (or just 4)
- 05 blink on (or just 5)
- 07 reverse video on (or just 7)
- 08 nondisplayed (invisible) ( or just 8 )
- 22 normal
- 23 no-standout
- 24 no-underline

- 27 no-reverse
- 30 black foreground
- 31 red foreground

- 33 yellow foreground
- 34 blue foreground
- 35 magenta foreground
- 36 cyan foreground

ESC[=#;7h or (Put screen in indicated mode where # is) ESC[=h or (0 for 40 x 25 black & white) ESC[=0h or (1 for 40 x 25 color) ESC[?7h (2 for 80 x 25 b&w)
- 3 for 80 x 25 color
- 4 for 320 x 200 color graphics
- 5 for 320 x 200 b & w graphics
- 6 for 640 x 200 b & w graphics

ESC[=#;7l or ESC[=l or (Resets mode # set with above command) ESC[=0l or ESC[?7l
Keyboard Reassignments: ESC[#;#;...p (Keyboard reassignment. The first ASCII) or ESC["string"p (code defines which code is to be) or ESC[#;"string";#; (changed. The remaining codes define) #;"string";#p (what it is to be changed to)
E.g. Reassign the Q and q keys to the A and a keys (and vice versa). ESC [65;81p (A becomes Q) ESC [97;113p (a becomes q) ESC [81;65p (Q becomes A) ESC [113;97p (q becomes a)
E.g. Reassign the F10 key to a DIR command.
ESC [0;68;"dir";13p (The 0;68 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,F4=62,F5=63 F6=64,F7=65,F8=66,F9=67,F10=68
