ANSI.SYS is a device driver in MS-DOS (and related operating systems) that provides extra console functions through ANSI escape codes. It is partially based upon a subset of the terminal control standard proposed by the ANSI X3L2 Technical Committee on Codes and Character Sets (the "X3 Committee"). A device driver, often called a driver for short, is a computer program that enables another program (typically, an operating system) to interact with a hardware device. ...

Once loaded, ANSI.SYS enabled codes that changed the colors of the cursor and characters on the screen, or enabled software programs to move the cursor up or down lines, enabled blinking text, and similar text graphics features. Using this driver, text could be displayed in 16 different colors ("foreground" colors), with 8 optional background colors. It also allowed for the changing of the video mode from standard 80x25 text mode to a number of different graphics modes (i.e. 320x200, 640x200, 40-column text mode) depending on the which video graphics card was installed. A cursor is a movable marker that indicates a position. ...
A text mode program communicates with the user by only displaying text and possibly a limited set of predefined semi-graphical characters, which allow to draw rudimentary boxes around portions of text, either to highlight the content or to simulate widget or control interface objects found in GUI programs. ...
An interesting feature about ANSI.SYS was that it allowed for the remapping of any key on the keyboard in order to perform shortcuts or macros for complex instructions. This feature was also used by evildoers to create simple trojans out of text files called "ANSI Bombs" laced with nefarious keyboard remaps. A number of antivirus utilities were written to ensure that, for example, the F3 function key wasn't remapped to DEL *.* or FORMAT C: and the N-key (for no) wasn't remapped to Y.

ANSI.SYS was required to run some software that used its cursor and color control functions. It could also be used to enable elaborate color codes in the command.com prompt. These uses were overshadowed by the use of ANSI.SYS in BBSes; ANSI escape codes were used to enable BBSes to send elaborate text graphics more elaborate than ASCII art, and to control the cursor in ways that were used in a number of online games and similar features.
