Problems Installing the Com Port Adapters
Windows does not like Com ports with the same name, and some devices might hang onto a com port
when not in use. Here is how to clean and remove problem ports.
Option 1
Devices that have been installed but are not currently available are "phantom devices". These devices are
not usually displayed in the device manager, but can be made to be displayed.
This allows device properties to be changed or devices to be uninstalled even though the device is not
physically connected to the PC.
Control Panel
System Properties
"Advanced" option and click "Environment Variables"
In the System Variables sections, click "New"
