A terminal mode is one of a set of possible states of a terminal or pseudo terminal character device in Unix-like systems and determines how characters written to the terminal are interpreted. In cooked mode data is preprocessed before being given to a program, while raw mode passes the data as-is to the program without interpreting any of the ...

The terminal interface provided by Unix 32V and Seventh Edition Unix, and also presented by BSD version 4 as the old terminal driver, was a simple one, largely geared towards teletypewriters as terminals. Input was entered a line at a time, with the terminal driver in the operating system (and not the terminals themselves) providing simple line ...
A block-oriented terminal or block mode terminal is a type of computer terminal that communicates with its host in blocks of data, as opposed to a character-oriented terminal that communicates with its host one character at a time. A block-oriented terminal may be card-oriented, display-oriented, keyboard-display, keyboard-printer, printer or ...
Pseudoterminals as they are used by script unix command that records user's input for replaying it later.. In some operating systems, including Unix-like systems, a pseudoterminal, pseudotty, or PTY is a pair of pseudo-device endpoints (files) which establish asynchronous, bidirectional communication channel (with two ports) between two or more processes.
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 ).
The EOT character is used in legacy communications protocols by mainframe computer manufacturers such as IBM, Burroughs Corporation, and the BUNCH.Terminal transmission control protocols such as IBM 3270 Poll/Select, or Burroughs TD830 Contention Mode protocol use the EOT character to terminate a communications sequence between two cooperating stations (such as a host multiplexer or Input ...
A pseudoterminal ("pseudo TTY" or "PTY") is a pair of pseudo-devices – a slave and a master – that provide a special sort of communication channel. The slave pseudo-device emulates a physical computer text terminal (like, e.g. the DEC VT100) it can read and write text as though it was such a physical terminal.
