The Free On-line Dictionary of Computing (18 March 2015):

start bit A bit which signals the start of transmission of a character on a serial line. For an RS-423 signal, the line is normally at logical zero which there is no data and the start bit is a logical one. The zero-one transition tells the receiver when to start sampling the signal to extract the data bits. [Is this upside-down?] (1995-02-02)
