	Definition:	\Morse" code"\ (Teleg.) The telegraphic code, consisting of dots, dashes, and spaces, invented by Samuel B. Morse. The Alphabetic code which is in use in North America is given 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. Note: {Alphabet} A .- H .... O . . V ...- B - . . . I .. P ..... W .-- C .. . J -.-. Q ..-. X .-.. D -.. K -.- R . .. Y .. ..

	Definition:	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.

Intercharacter space are as long as -'s. Spaces between words are as long as seven '.'s.
