How to Implement inter-process communication 1. IntroductionIn WindowsProgramProcesses often need to exchange data for data communication. Win32 API provides many functions that allow us to conveniently and efficiently communicate between processes.

The serial communication programming methods used include: using communication controls, embedding assembly in advanced languages, and using API functions. In these methods, use the serial port communication compiled by the API Function Program
