The data link escape character was intended to be a signal to the other end of a data link that the following character is a control character such as STX or ETX. For example a packet may be structured in the following way <STX> <PAYLOAD> <ETX>.
Control-C is often used to interrupt a program or process, a standard that started with Dec operating systems. [citation needed] In TOPS-20, it was used to gain the system's attention before logging in. mIRC uses ETX as the escape character to start a command to set the color.
The Basic Latin Unicode block, [3] sometimes informally called C0 Controls and Basic Latin, [4] is the first block of the Unicode standard, and the only block which is encoded in one byte in UTF-8.
In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
ISO 1745:1975 Information processing – Basic mode control procedures for data communication systems is an early ISO standard defining a Telex-oriented communications protocol that used the non-printable ASCII transmission control characters SOH (Start of Heading), STX (Start of Text), ETX (End of Text), EOT (End of Transmission), ENQ (Enquiry), ACK (Acknowledge), DLE (Data Link Escape), NAK ...
Next to this name, a character can have one or more formal (normative) alias names. Such an alias name also follows the rules of a name: characters used (A-Z, -, 0-9, <space>) and not used (a-z, %, $, etc.). Alias names are also unique in the full name set (that is, all names and alias names are all unique in their combined set).
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use. Important messages could be ...
