  THE MORSE CODE & THE CONTINENTAL CODE - TELEGRAPH & SCI INSTRUMENT MUSEUMS
The original "MORSE CODE" used by Samuel Morse since the 1840's to allow letters to be sent as short electrical signals (dots) and long electrical signals (dashes) along with some embedded spaces was also called the "AMERICAN" MORSE CODE.
The early "Morse Code" was well suited for this form of communication but could not easily be used for radio telegraphic communication due to the embedded spaces which were actually an integral part of several letters.
The original "Morse Code" was replaced in England in the 1800's by a somewhat similar code which eliminated all of the embedded spaces and long dashes within letters that were found in many of the letters in the original Morse code.

  The First Printing Telegraphs   (Site not responding. Last check: )
The idea was to use the incoming telegraph signals to spin the wheel by fixed steps until the correct character faced the paper, and to then propel that character onto an inked tape located in front of the paper.
In the case of the Baudot Code, twenty-six of these combinations were used for letters of the alphabet, leaving eight spare combinations for an idle code, a space code, a letter-shift code, and so on.
this dilemma, the letter-shift code was used to emulate the shift key on a typewriter by instructing the receiver that any subsequent codes were to be treated as uppercase characters (in this context, uppercase was used to refer to numbers, punctuation, and special symbols).

 The Electromagnetic Telegraph
Telegraphs made with one would work in a room, but would fail completely to work over only a short line, as many telegraph enthusiasts found to their disappointment.
Telegraph trials were also made on the Saxon State Railways between Leipzig and Dresden by Weber of Göttingen and Steinheil in 1838, applying the telegraph to train operation, says M. von Weber in 1867, who also claims (probably erroneously) that the earth return was discovered there.
Cooke and Wheatstone both worked on electrically-released dial telegraphs on which a hand would point to the desired message or character, so that skilled operators (and their wages) would not be required, or that the telegraph could be operated by the general public.

 Alfred Vail Summary
By 1838 the partners were demonstrating their perfected telegraph; the superb mechanics of the system were largely Vail's contribution.
Morse originally devised a cipher code similar to that used in existing semaphore telegraphs, by which words were assigned three or four digit numbers and entered into a codebook.
Alfred Vail is often credited with having developed the telegraph code known as the Morse code.

 Commercial Telegraphic Code Books
Code books were used in the era of telegraphs (from 1845 until well into the second half of the 20th century) to shorten telegrams, which were paid for by the word.
Codes are still in use to convey very specialized and formulaic information in such fields as weather reporting, stock market reporting, aviation flight control, and epidemiological field reporting.
In China, however, telegraphic codes are (or have recently been) widely used, since the usual writing system for Chinese is not directly usable with the telegraph.

 Morse code Summary
This two-symbol, dot-and-dash code is capable of representing the characters of the alphabet by varying the number of symbols between one and four.
In order to use the code, telegraph operators punched a simple key to open and close an electric circuit; a short keystroke was a dot, while a longer keystroke was a dash.
In general, any code representing written symbols as variable length signals can be called a Morse code, but the term is used specifically for the two kinds of Morse code used for the English alphabet and associated symbols.

This code is variously called ``dian4bao4ma3,'' ``Standard Telegraphic Code,'' ``Chinese Commercial Telegraph Code,'' ``Chinese Commercial Code,'' and ``telecode,'' and I have seen it abbreviated STC, CCC, and CTC.

 History of Communications - through the ages and into the next century...
The idea for the electric telegraph was not thought up in a scientific laboratory, but on the deck of a sailing ship called the Scully, in the middle of the Atlantic Ocean.
The telegraph was a success, In 1874, engineer and inventor Thomas Edison invented quadruplex telegraphy, where two messages could be sent in each direction at one time.
Because of this and the invention of the teleprinting machines during the mid-1920s the Morse Code telegraph system wasn't needed anymore.

 Telegraph Key And Sounder, 1850s, 1860s
A morse code was invented that contained a series of dots and dashes for every letter and every number which was known as the morse code.
It's important to remember that the telegraph, which quickly spread from 1844 on and the telephone which was invented in 1876, required multiple operators to relay messages and patch calls and dispatches through.
The telegraph office would then covert the morse code to a written message and hand deliver the telegram to the person it was addressed to on foot.
