Baudot code

The Baudot code is the original character set for the teletype code. It was developed by the French engineer Jean-Maurice-Émile Baudot (1845 to 1903) and later further developed by Donald Murray (1865 to 1945) for alphanumeric keyboards.

The original Baudot code was designed for a keyboard with five keys that determined valence and could be either pressed or not pressed. The resulting code was a 5-bit code to which 32 different valences were assigned. This code was called CCITT-1 or International Alphabet 1 (IA1).

Since not all letters, numbers, punctuation marks and control characters could be represented with the 32 significances, Baudot worked with double assignment and two sets of characters. On the first were the letters and the control characters for carriage return and line feed, on the second the digits with the punctuation marks. Two valences were reserved for switching letters/digits and digits/letters.

The later code adapted by Murray to alphanumeric keyboards is the CCITT-2 or the International Alphabet 2( IA2).
