Can PHP achieve serial port real-time communication? I have found many, many examples on the Internet. They are all writers. The code does not work at all, or it is mainly for LINUX. Is there anyone who has done similar projects who has detailed solutions and pointers? Thank you very much!

The echo is too slow. For a 10-digit number, you need to wait for 1 minute to return it. It cannot be displayed dynamically, and it will not be read when it is looped. This is not what I want. It is no different from the dio on the Internet, and this framework is too big. Is there a simple and reliable method?
