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. Source: Internet
It was already proposed by D'Arlincourt in 1870. citation Instead of wasting time and money in patent disputes on the start-stop method, Kleinschmidt and the Morkrum Company decided to merge and form the Morkrum-Kleinschmidt Company in 1924. Source: Internet
Computer processing power and amounts of available memory were usually insufficient to provide a constant stream, so tape drives were typically designed for so called start-stop operation. Source: Internet
The degree of distortion of a start-stop modulation (or demodulation) is usually expressed as a percentage. Source: Internet
The Model 3 tape printer, Creed’s first combined start-stop machine, was introduced in 1927 for the Post office telegram service. Source: Internet
The RS-232 standard specifies an asynchronous, start-stop mode of data transmission where data is sent in groups (characters) of 7 or 8 bits. Source: Internet
