RM520N-GL how to enable COM Port Windows?

yes, direct install in m2 port on notebook

Dear @nik135
If install on PC directly, it need notebook to support it.
It need corresponding driver, we don’t have it.

When setting up the RM520N-GL COM port in Windows, checking keyboard input can also help confirm your system is responding correctly. A quick keyboard NKRO test can check whether multiple key presses are detected properly. This is useful when testing keyboard behavior after changing Windows device settings.
