It is widely used in the connection of computer serial interface and peripheral equipment, connecting cable, mechanical and electrical characteristics, signal function and transmission process. The serial port is a hardware module necessary for debugging and developing the embedded device, the most common serial port protocol of the embedded device is RS232, usually, an RS-232 interface appears in a form of 9 pins (DB-9) or 25 pins (DB-25), and later, an IBM PC simplifies the RS232 into a DB-9 connector with 9 pins, so that the standard of reality is formed. The RS-232 port of the industrial control generally only uses three lines of RXD, TXD and GND. However, when the embedded device is designed into hardware, two devices communicate with each other, and the RXD port of the first device is connected with the TXD port of the second device, so that the direct connection and the cross of serial port lines are caused. Direct connection of serial port lines means that 2 pins and 3 pins of the serial port, namely RT pins and TX pins, are directly corresponding, and cross lines mean that RT pins and TX pins are in cross correspondence.
