The company's project is close to the end. From the very beginning, the SerialPort has been used. So, let's make a summary. At the beginning of the project, I never touched the SerialPort. I don't know how to get started, such as the most basic portname (communication port), baudrate (baud rate), and parity (parity) databits (Data bit length) and stopbits (Stop bits) do not know, and later, the Internet Google others' experience, know the most basic
