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.
The standard ANSI.SYS is very slow as it maps escape sequences to BIOS calls (which managed to be designed so that two calls were needed to put a character on the screen and move the cursor right). Several companies made third-party replacements such as NANSI.SYS [ 2 ] that interface directly with the video memory , in a similar way to most DOS ...
Curses is designed to facilitate GUI-like functionality on a text-only device, such as a PC running in console mode, a hardware ANSI terminal, a Telnet or SSH client, or similar. Curses-based software is software whose user interface is implemented through the curses library, or a compatible library (such as ncurses).
For example, the sequence of code 27 10, followed by the printable characters "[2;10H", would cause a Digital Equipment Corporation VT100 terminal to move its cursor to the 10th cell of the 2nd line of the screen. Several standards exist for these sequences, notably ANSI X3.64, but the number of non-standard variations is large.
The VT100 is a video terminal, introduced in August 1978 by Digital Equipment Corporation (DEC). It was one of the first terminals to support ANSI escape codes for cursor control and other tasks, and added a number of extended codes for special features like controlling the status lights on the keyboard.

TheDraw is a text editor for MS-DOS to create ANSI and animations as well as ASCII art.The editor is especially useful to create or modify files in ANSI format and text documents, which use the graphical characters of the IBM ASCII code pages, because they are not supported by Microsoft Windows anymore.
