Abstract
Serial communication is a simple means of sending data to long distances quickly and reliably. The most commonly used serial communication method is based on the RS232 standard. In this standard data is sent over a single line from a transmitting device to a receiving device in bit serial format at a prespecified speed, also known as the Baud rate, or the number of bits sent each second. Typical Baud rates are 4800, 9600, 19200, 38400, etc. Data in serial asynchronous communication can either be sent using the standard RS232 protocol or two devices can simply be connected together provided they satisfy the logic gate interface rules (e.g., TTL to TTL, or TTL to CMOS, etc.). In the RS232 protocol, a logic HIGH is ...
