ANSI escape sequences are a standard for in-band signaling to control cursor location, color, font styling, and other options on video text terminals and terminal emulators. Certain sequences of bytes , most starting with an ASCII escape character and a bracket character, are embedded into text.
Example of long-form ANSI artwork. ANSI art is a computer art form that was widely used at one time on bulletin board systems.It is similar to ASCII art, but constructed from a larger set of 256 letters, numbers, and symbols — all codes found in IBM code page 437, often referred to as extended ASCII and used in MS-DOS and Unix [1] environments.
On some terminals, these characters are not available at all, and the complexity of the escape sequences discouraged their use, so often only ASCII characters that approximate box-drawing characters are used, such as - (hyphen-minus), | (vertical bar), _ , = and + in a kind of ASCII art fashion.
In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. [3]Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth ...
ANSI.SYS is a device driver in the DOS family of operating systems that provides extra console functions through ANSI escape sequences.It is partially based upon a subset of the text terminal control standard proposed by the ANSI X3L2 Technical Committee on Codes and Character Sets (the "X3 Committee").
These systems used a VT52-based screen driver in an era when ANSI escape codes had already become almost universal. This version added several new commands including the ability to select colors. This version added several new commands including the ability to select colors.
American National Standards Institute (ANSI) standard ANSI X3.64 defines a standard set of escape sequences that can be used to drive terminals to create TUIs (see ANSI escape code). Escape sequences may be supported for all three cases mentioned in the above section, allowing arbitrary cursor movements and color changes. However, not all ...
Christian Wirth (born in the 1970s), better known by the pseudonym RaD Man, is an American computer artist and historian.He works in the field of ANSI art, a method of creating art using a limited set of text characters and color escape codes based loosely on the relevant ANSI standard (X3.64: Control Sequences for Video Terminals and Peripherals).
