B4J Question Creating a Virtual Com Port?

I have an idea for a B4J app that requires that the app creates a VCOM port for other pc apps to connect to.
Is this possible? I guess maybe not but maybe I am wrong.

If not possible, I could also realize this idea if I can transfer data between the B4J app and a c# windows app.
I don't think I can compile as a DLL, so what approach would present itself for this scenario?

Thanks
