17.4 Terminal Modes

This section describes the various terminal attributes that control how input and output are done. The functions, data structures, and symbolic constants are all declared in the header file `termios.h'.

Don't confuse terminal attributes with file attributes. A device special file which is associated with a terminal has file attributes as described in 14.9 File Attributes. These are unrelated to the attributes of the terminal device itself, which are discussed in this section.

17.4.1 Terminal Mode Data Types		The data type struct termios and related types.
17.4.2 Terminal Mode Functions		Functions to read and set the terminal attributes.
17.4.3 Setting Terminal Modes Properly		The right way to set terminal attributes reliably.
17.4.4 Input Modes		Flags controlling low-level input handling.
17.4.5 Output Modes		Flags controlling low-level output handling.
17.4.6 Control Modes		Flags controlling serial port behavior.
17.4.7 Local Modes		Flags controlling high-level input handling.
17.4.8 Line Speed		How to read and set the terminal line speed.
17.4.9 Special Characters		Characters that have special effects, and how to change them.
17.4.10 Noncanonical Input		Controlling how long to wait for input.
