RS-232
Introduction
The basic approach of RS-232 serial transmission is that of a UART.
UART stands for Universal Asynchronous Receiver/Transmitter.
It is the standard method of translating a serial communication
stream into the parallel form used by computers. RS-232 is a
UART that has a specific standard defined for start, stop, break,
data, parity and pin names.
RS-232 baud rate generator
The RS-232 is an asynchronous transmission scheme and so the cor-
rect clock rate must be defined prior to transmission to ensure that
the data is transmitted and received correctly. The RS-232 baud rate
can range from 1200 baud up to 115200 baud. This is based on a ...
