  Morse code \Morse" code"\ (Teleg.)
     a telegraphic code, in which dots, dashes, and spaces
     represent letters, numbers, and other elements of text. The
     original code was invented by Samuel B. Morse. The code now
     mostly used is the International Morse code, also referred
     to simply as the Morse code.
     [1913 Webster +PJC]
  
     Note: The present International Morse Code is given in the
           table below. There are no spaces in the International
           Morse Code.

           The Alphabetic code which was originally in use in
           North America is given in the table below. In length,
           or duration, one dash is theoretically equal to three
           dots; the space between the elements of a letter is
           equal to one dot; the interval in spaced letters, as O
           . ., is equal to three dots. There are no spaces in any
           letter composed wholly or in part of dashes. Alphabet

           The Morse code was used chiefly with the electric
           telegraph, but is also employed in signalling with
           flags, lights, etc.
           [Webster 1913 Suppl. +PJC]

From WordNet (r) 3.0 (2006) :

  Morse code
      n 1: a telegraph code in which letters and numbers are
           represented by strings of dots and dashes (short and long
           signals) [syn: Morse, Morse code, international Morse
           code]

From The Free On-line Dictionary of Computing (18 March 2015) :

  Morse code
  
      A coding system invented by Samuel A. Morse,
     for use in sending character data over extremely low-quality
     pathways -- such as telegraphs and low-quality radio.  Morse
     code expresses characters as pulses of different durations.
     Short signals are called "dots" and long signals are calles
     "dashes".  The coding assigns shorter sequences to the most
     frequently used characters.
  
     American Morse code is the first and original Morse code
     character set.  Character sets adapted to other languages
     were developed later.
  
     American Morse Code:
  
      A . __        J . .          S . . .       1 . __ __ .
      B __ . . .    K __ . __      T __          2 . . __ . .
      C . .  .      L ___          U . . __      3 . . . __ .
      D __ . .      M __ __        V . . . __    4 . . . . __
      E .           N __ .         W . __ __     5 __ __ __
      F . __ .      O .  .         X . __ . .    6 . . . . . .
      G __ __ .     P . . . . .    Y . .  . .    7 __ __ . .
      H . . . .     Q . . __ .     Z . . .  .    8 __ . . . .
      I . .         R .  . .       0 ____        9 __ . . __
  
     Where . is a short pulse, __ a long pulse, ___ a very long
     pulse and ____ a extra long pulse.  There are also long and
     short spaces character-internal.  Intercharacter spaces are
     very long and interword spaces are extra long.  There is no
     standarisation in these durations, and they vary depending on
     the coder's preference and on the quality of the line.
  
     Continental Morse Code or International Morse Code is a widely
     used de-facto standard.  This table summarises the Western
     European usage of Continental Morse Code:

       (2) Used only in German; not in Dutch.
       (3) also: 'divided by'
       (4) before and after the word to be underlined
       (5) purportedly replaced by -.--.- for both "(" and ")"
       (6) both and invitation to any station to start transmission
       (7) also used as spacing between parts of transmission
       (8) also an invitation to one station in particular to start
           transmission
       (9) connection will be closed.
       (10) in fractions, for example.
       (11) A-ring ?
  
     Where '.' is a short pulse, '-' a long one.  A '-' is three
     times as long as a '.'; character-internal spaces are as long
     as '.'s.  Intercharacter space are as long as -'s.  Spaces
     between words are as long as seven '.'s.
