The first bit transmitted in asynchronous data transmission to unequivocally indicate the start of the word.
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
In asynchronous communications, the bit transmitted before each character.
In one embodiment of the present invention, preamble and synchronization word patterns are selected such that the start bit of the first byte of data that follows the synchronization word synchronizes with the start bit clocking signal of the baseband receiving serial port.
