baudot code


Baudot code

[bȯ′dō ‚kōd] (communications) A teleprinter code that uses a combination of five or six marking and spacing intervals of equal duration for each character.

Baudot code

(communications)(For etymology, see baud) A character setpredating EBCDIC and used originally and primarily on paper tape. Use of Baudot reportedly survives in TDDs and someHAM radio applications.

In Baudot, characters are expressed using five bits. Baudotuses two code sub-sets, the "letter set" (LTRS), and the"figure set" (FIGS). The FIGS character (11011) signals thatthe following code is to be interpreted as being in the FIGSset, until this is reset by the LTRS (11111) character.

Where CR is carriage return, LF is linefeed, BELL is thebell, SP is space, and STOP is the stop character.

Note: these bit values are often shown in inverse order,depending (presumably) which side of the paper tape you werelooking at.

Local implementations of Baudot may differ in the use of #,STOP, BELL, and '.

baudot code

Pronounced "baw-doh." One of the first standards for international telegraphy developed in the late 19th century by Emile Baudot. It uses five bits per character. See baud.
