That's what I was afraid of, thank you Erel.

I found some code here: https://stackoverflow.com/questions...ort-given-its-comx-name-under-windows-in-java

That requires jna to access. Latest version is available here: https://github.com/java-native-access/jna

You need to download the jna jar and the jna-platform jar and copy them to your additional libraries folder. The java code will only work for windows.

You may need to change the references in the #AdditionalJar declarations in the main module if the jna download is a newer version.

In the attached demo app the GetAll method returns a B4x Map, converted from the Hashmap returned by the java code and seems to contain connected devices, The Get method I left so you could try it, but it only appears to return registered devices and then only if it has a friendly name (which my COM1 doesn't) so I am not sure if it will be useful or not.
