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 File Attributes. These are unrelated to the attributes of the
terminal device itself, which are discussed in this section.
Mode Data Types: The data type struct termios and
related types.
Mode Functions: Functions to read and set the terminal
attributes.
Setting Modes: The right way to set terminal attributes
reliably.
Input Modes: Flags controlling low-level input handling.
Output Modes: Flags controlling low-level output handling.
Control Modes: Flags controlling serial port behavior.
Local Modes: Flags controlling high-level input handling.
Line Speed: How to read and set the terminal line speed.
Special Characters: Characters that have special effects,
and how to change them.
