I have a hardware device,Data from the com port, I want Read its data in the UE4.

I try to use the WINAPI ReadFile, it does not work in ue4.But on the outside of the UE4, it work properly.
This looks very strange.

Does anyone know what’s going on?

Same way you would in any other C++ program.

For example: GitHub - wjwwood/serial: Cross-platform, Serial Port library written in C++

If you want information on linking to the external library from your project, see this question: https://answers.unrealengine.com/questions/197667/how-do-you-statically-link-an-external-dlldylib-to.html
