Generally, an escape character is not a particular case of (device) control characters, nor vice versa.If we define control characters as non-graphic, or as having a special meaning for an output device (e.g. printer or text terminal) then any escape character for this device is a control one.
Some modern text file formats (e.g. CSV-1203 [10]) still recommend a trailing EOF character to be appended as the last character in the file. However, typing Control + Z does not embed an EOF character into a file in either DOS or Windows , nor do the APIs of those systems use the character to denote the actual end of a file.

It was a continuation of a series of character coding standards, the first one being ECMA-6 from 1965, a 7-bit standard from which ISO 646 originates. The name "ANSI escape sequence" dates from 1979 when ANSI adopted ANSI X3.64. The ANSI X3L2 committee collaborated with the ECMA committee TC 1 to produce nearly identical standards.
Caret notation is used to describe control characters in output by many programs, particularly Unix terminal drivers and text file viewers such as more and less commands. Although the use of control-codes is somewhat standard, some uses differ from operating system to operating system, or even from program to program.
The BBC Micro could utilize the Teletext 7-bit character set, which had 128 box-drawing characters, whose code points were shared with the regular alphanumeric and punctuation characters. Control characters were used to switch between regular text and box drawing.
