Baudot code
Proper noun
Meaning
Baudot code
An early character encoding used in telegraphy, representing each letter in the alphabet by five bits (binary digits).
Examples
A form of control characters were introduced in the 1870 Baudot code : NUL and DEL.
AT&T developed a competing network called " TWX " which initially also used rotary dialing and Baudot code, carried to the customer premises as pulses of DC on a metallic copper pair.
Following the start bit, the character is represented by a fixed number of bits, such as 5 bits in the Baudot code, each either a mark or a space to denote the specific character or machine function.
The Baudot code was used asynchronously with start and stop bits : the asynchronous code design was intimately linked with the start-stop electro-mechanical design of teleprinters.
The Baudot code was never used in teleprinters.
Then came the teleprinter (ca. 1910) with its punched-paper use of Baudot code on tape.
