Pseudo-Terminals
================

   A "pseudo-terminal" is a special interprocess communication channel
that acts like a terminal.  One end of the channel is called the
"master" side or "master pseudo-terminal device", the other side is
called the "slave" side.  Data written to the master side is received
by the slave side as if it was the result of a user typing at an
ordinary terminal, and data written to the slave side is sent to the
master side as if it was written on an ordinary terminal.

   Pseudo terminals are the way programs like `xterm' and `emacs'
implement their terminal emulation functionality.
