It is suitable for data transfer rate in the 0 ~ 20000b/s within the scope of communication. The standard serial communication interface of the relevant issues, such as the signal line features, electrical characteristics have been clearly defined. Since the passage of equipment manufacturers have production and standard RS-232C compatible communications equipment, so that it as a standard has been in the computer communication interface is widely used.
