Specifies control functions, and their coded representations, for use in text communications.

This International Standard defines the control functions, and their coded representations needed, for use in text communication.

Section 2 specifies the control functions for text in page-image format, Section 3 specifies the control functions for formatted and formattable text.

The control functions, with the exception of two, have been taken from ISO 6429. The definitions of the control functions in this International Standard are, in general, more specific than the corresponding definitions in ISO 6429.

The specifications in this International Standard apply to the interchange of text in the form of binary-coded representations of graphic characters and control functions. They are not intended for the actual processing of text.

Although, in general, text consists of characters and pictures, this International Standard applies only to text made up of characters.

The coded representations defined in this International Standard are intended for use when the control functions concerned are embedded in the communicated text, not when they are separated from the text as elements of a communication protocol, for example.

This International Standard does not define any control functions required for controlling the process of communication.
