 17.8 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.
