Definition:Baudot Code

Definition
The Baudot code is a character encoding for telegraphy.

Each character in the alphabet is represented by a series of five bits, sent over a transmission line.

The columns are arranged in the order they are, that is:
 * $\text {V}$, $\text {IV}$, $\text {I}$, $\text {II}$, $\text {III}$

because that is how they were arranged on the original machines that were used to perform the encoding.


 * $\dagger \quad$ After receiving this code, all following codes are interpreted as digits until the next Letter code.
 * $\ddagger \quad$ After receiving this code, all following codes are interpreted as letters until the next digit code.
