uucp

   <networking, messaging> (uucp) A {Unix} utility program and
   {protocol} that allows one Unix system to send files to
   another via a {serial line} which may be a cable going
   directly from one machine's {serial port} to another's or may
   involve a {modem} at each end of a telephone line.

   Software is also available to allow uucp to work over
   {Ethernet} though there are better alternatives in this case,
   e.g. {FTP} or {rcp} for file transfer, {SMTP} for {electronic
   mail} or {NNTP} for {news}.

   The term is now also used to describe the large international
   network which uses UUCP to pass {Usenet} {news} and
   {electronic mail}, also known as "UUCPNET".

   {Unix manual page}: uucp(1).

   See also {cu}, {uuencode}.
