Currently, serial ports are commonly used data transmission channels between computer and external control systems in various control systems for laboratory and industrial applications. As serial communication is convenient and easy to use, it is widely used. However, the use of serial communication imposes restrictions on real-time performance, speed, and data size. While the computer's parallel port transfers data at a time by eight (one byte) or more, because of the large amount of transmissi
