Mac OS X Panther in a Nutshell, 2nd Edition

Name

stty

Synopsis

stty [options] [modes]

Sets terminal I/O options for the current device. Without options, stty reports the terminal settings, where a ^ indicates the Control key, and ^' indicates a null value. Most modes can be switched using an optional preceding dash (-, shown in brackets). The corresponding description is also shown in brackets. As a privileged user, you can set or read settings from another device using the syntax:

stty [options] [modes] < device

stty is one of the most complicated Unix commands. The complexity stems from the need to deal with a large range of conflicting, incompatible, and nonstandardized terminal devices—everything from printing teletypes to CRTs to pseudoterminals for windowing systems. Only a few of the options are really needed for day-to-day use. stty sane is a particularly valuable one to remember.
