Additional Guest PC COM Ports Do Not Work After You Add Them

After you create an additional COM port in the guest PC settings, that COM port does not work when you start the guest PC.

This behavior occurs because the host computer does not have a COM port that corresponds to the port that you created for the guest PC.

When you configure your guest PC settings, you must configure COM port devices only for the COM ports that are present on the host computer. You can configure up to 256 COM ports in a guest PC, but only those devices that correspond to COM port devices physically installed on the host computer will function.

To work around this issue, either remove the guest PC COM ports that do not correspond to actual COM port devices on the host computer, or add additional COM port devices on the host computer.
