| A <dfn>pseudo-terminal</dfn> is a special interprocess communication channel |
| that acts like a terminal. One end of the channel is called the |
| <dfn>master</dfn> side or <dfn>master pseudo-terminal device</dfn>, the other side |
| is called the <dfn>slave</dfn> 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. |
| |
| <p>Pseudo terminals are the way programs like <code>xterm</code> and <code>emacs</code> |
| implement their terminal emulation functionality. |
