What's that little icon badge over the (real) COM1 port? I don't recall ever seeing that before. What is the status of that device?
You have a bit of a mess there, if you haven't noticed. The PPS config says 57.6k, your device manager tab says 9.6k, so you have incompatible configurations there.
Personally, if you're not using those other 3 COM ports (which I can't imagine you are), I'd disable them in the device manager so they are out of the way. Once you have no active builtin com ports, I'd plug the base in again and see if you can't get it correctly configured when it's the only thing going.
