(1) A character whose occurrence in a particular context specifies a control function. . (2) A character, other than a graphic character, that affects the recording, processing, transmission, or interpretation of text. X/Open. See nonprinting character.
Any of the 32 ASCII characters that do not print on your screen or printer. These characters are usually used to control your computer.
a) [ISO] A control function, the coded representation of which consists of a single bit combination. b) [IBM] A character whose occurence in a particular context initiates, modifies, or stops a control function.
A character typed by pressing a key while the Control key is pressed. For instance, a Control-H is typed by pressing the H key while pressing the Control key.
A character that denotes the start, modification, or end of a control function. A control character can be recorded for use in a subsequent action, and it can have a graphic representation.
a character that has special interpretation in an input/output context. Examples are backspace and newline.
A character whose occurrence in a particular context initiates, modifies, or stops a control function. In the ASCII code, any of the 32 characters in the first two columns of the standard code table. See also: communication control character
A character which does not have a printable or displayable representation, but, when encountered in a stream of characters, performs a specific action. In ASCII the codes for these characters are in the range [0,31] or it is 127; each character also has a two- or three-character symbol for representing it in plain text. The common PC keyboard for U.S. use has special keys for some, i.e., ESC, CR, BS, HT, DEL. Each control character in ASCII can be generated by pressing the Ctrl key simultaneously with another key. For more information see ASCII, Key Codes & ANSI Commands.
A control character is a character that you type by holding down the CTRL key. Some control characters also have their own keys, so that you can type them without using CTRL. For example, RET, TAB, ESC and DEL are all control characters. See section Types d'entr'ees utilisateur.
ASCII characters to indicate carriage return or tab or backspace; typed by depressing a key and the control key at the same time
a character that, instead of printing a symbol, causes an action to take place, like moving down to the next line on the display
a non-printing character in computing
a special character that is used for string alignment
Nonprinting character combination. CP/M interprets some control characters as simple commands such as line editing functions. To enter a control character, hold down the CONTROL key and strike the specified character key.
ASCII characters with octal codes 0 through 037, and also code 0177, do not have graphic images assigned to them. These are the Control characters. To type a Control character, hold down the CTRL key and type the corresponding non-Control character. RET, TAB, ESC, LFD and DEL are all control characters. See User Input. When you are using the X Window System, every non-control character has a corresponding control character variant.
Carat-shaped character located on the keyboard
The key to the left of the "A" on the keyboard which is used in addition to another key. This expands the Possible number of values that the keyboard may send to the computer.
A control character is a character that you type by holding down the CTRL key. Some control characters also have their own keys, so that you can type them without using CTRL. For example, RET, TAB, ESC and DEL are all control characters. See section B.5 Kinds of User Input.
A character you make by holding down the keyboard CTRL (Control) key while pressing a letter or another character key.
A character whose occurrence in a particular context starts, modifies or stops an operation that effects the recording, processing, transmission or interpretation of data.
A character that has some processing semantics attached which affects he processing of character following.
A character whose purpose is to control an action rather than to pass data to a program; ASCII control characters have an octal code between O and 37; normally typed by holding down the-CTRL key on a terminal keyboard while striking a character key.
one of the first 26 ASCII characters, generatedq
A character string, usually with an ASCII value between 0 and 31, used to communicate with devices such as printers, modems, and the like.
A character that is inserted into a data stream for signaling the receiving station to perform a function to identify the structure of the message. Newer protocols use bit-oriented control procedures.
In computing, a control character or non-printing character is a code point (a number) in a character set that does not in itself represent a written symbol. All entries in the ASCII table below 32 (technically the C0 control code set) and 127 are of this kind, including BEL (which is intended to cause an audible signal in the receiving terminal), SYN (which is a synchronization signal), and ENQ (a signal that is intended to trigger a response at the receiving end, to see if it is still present). The Unicode standard has added many new non-printing characters, for example the Zero-width non-joiner.
