APPENDIX D: Asynchronous Communication
Because each bit in asynchronous communications is sent consecutively, it is easy
to generalize asynchronous communications by stating that each character is
wrapped (framed) by pre-defined bits to mark the beginning and end of the serial
transmission of the character. The data rate and communication parameters for
asynchronous communications have to be the same at both the transmitting and
receiving ends. The communication parameters are baud rate, parity, number of
data bits per character, and stop bits (usually listed in that order, like this:
9600,N,8,1).
