Before revision: Operation Before signalling will work, the sender and receiver must agree on the signalling parameters: Full or half-duplex operation The number of bits per character Endianness: the order in which the bits are sent The speed or bits per second of the line ( often incorrectly referred to as the Baud rate ).
