Description

These functions describe a general terminal interface for controlling asynchronous communications ports. A more detailed overview of the terminal interface can be found in termio(7I) , which also describes an ioctl(2) interface that provides the same functionality. However, the function interface described by these functions is the preferred user interface.

Each of these functions is now described on a separate manual page.
