  Baudot code - Wikipedia, the free encyclopedia
Baudot's original code, developed around 1874 is known as International Telegraph Alphabet No 1, and is no longer used.
Around 1901 Baudot's code was modified by Donald Murray by re-ordering the characters, adding extra characters and shift codes.
The Russian version of Baudot code (MTK-2) used three shift modes, the Cyrillic letter mode was activated by the character (00000) unused in original ITA2.

 Emile Baudot By Johnny Jung
Emile Baudot was born in 1845, Magneux, France and died on March1903, Sceaux.
Baudot used a different type of code for his system because Morse code didn't lend itself to automation, this was due to the uneven length and size of bits required for each letter.
During this period of twenty years, Baudot installations multiplied in France and spread in foreign countries, everywhere assuring excellent service in doubling, tripling, or quadrupling the efficiency of the wires.

The Baudot code, named after its inventor Émile Baudot, is a character set predating EBCDIC and ASCII and used originally and primarily on teleprinters.
It was sent using a five-key keyboard where each key represented one bit of the five state signal.
FIGS (11011), LTRS (11111) and space (00100) are invariant, while CR (11000) and LF (00011), generally used as a pair, result in the same output when the tape is reversed.

In telecommunications the baud is a measure of symbols transmitted per second in a modulated signal.
It is named after Émile Baudot, the inventor of the Baudot code for telegraphy.
The term baud is sometimes misused to refer to "bits per second"; though it is possible for one event to carry one bit, it is more common to make more efficient use of bandwidth by transferring several bits—as many as sixteen—in one event.

Emile Baudot invented a new telegraph code, machine, and printer to allow more than one message to be sent on a single wire at the same time.
Baudot began life working on his father's farm but he didn't enjoy being a farmer, and joined France's Administration of Posts and Telegraphs in 1869.
Baudot's new system was based on a revolutionary technique that allowed multiple operators to send messages down the same wire simultaneously.

On June 17, 1874, Baudot patented, under the number 103,898 and the title "System of rapid telegraphy" his first apparatus, which was both multiple and really printing, since the conventional signals were translated automatically into typographic characters.
Baudot died on March 28, 1903, at Sceaux, France, near Paris, at the age of fifty-seven, after a long time illness.

The original Baudot code defined the familiar structure of a 5-level code set, using LTRS and FIGS case shifting, and became known as the International Telegraph Alphabet 1 (ITA1).
Another recognition of Baudot's contribution to data communications is the term "baud," which refers to bits-per-second speed of serial data.

 :: THE BAUDOT TELEGRAPH::   (Site not responding. Last check: 2007-09-19)
In Baudot's code, each letter was represented by a five-unit combination of current-on or current-off signals of equal duration; this represented a substantial economy over the Morse system of short dots and long dashes.
Thus, 32 permutations were provided, sufficient for the Roman alphabet, punctuation signs, and control of the machine's mechanical functions.
Baudot also invented (1894) a distributor system for simultaneous (multiplex) transmission of several messages on the same telegraphic circuit or channel.

 The First Printing Telegraphs
The two-channel paper tape technique pioneered by Sir Charles Wheatstone was subsequently extended to handle the Baudot Code.
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.
Unfortunately, none of these systems were tremendously robust or reliable, and they all suffered from major problems in synchronizing the transmitter and the receiver such that both knew who was doing what and when they were doing it.

 Teleprinter - Wikipedia, the free encyclopedia
The Baudot code was used asychronously with start and stop bits: the asynchronous code design was intimately linked with the start-stop electro-mechanical design of teleprinters.
When the line is broken, a teletype cycles continuously but prints nothing because it is receiving all zeros, the ASCII (or Baudot) NUL character.
Speed, intended to be roughly comparable to words per minute, was the standard designation introduced by Western Union for a mechanical teleprinter data transmission rate using the 5-bit baudot code that was popular in the 1940s and for several decades thereafter.

 The History of Data Cabling
The big difference is, that while the telegraph operators of the mid 19th Century could perhaps transmit 4 or 5 dots and dashes per second, computers now communicate at speeds of up to 1 Giga bit, or to put it another way, 1,000,000,000 separate 1’s and 0’s every second.
Not long after Morse's Telegraph, a French inventor called Emile Baudot developed a printing telegraph machine which used a typewriter style keyboard, this allowed virtually anyone to send and receive telegraph messages.
Despite its long running success, the Baudot five bit code could only use 'upper case', so it had to be replaced with something that would allow more alphanumeric characters to be used.
