Troubleshooting the USB Serial COM Port Number
4. To assign a port number less than 10, click on
<Advanced> . The Advanced Settings Window will
appear.
5. In the COM Port Number drop box, select which
COM port you wish to use. Make sure you select a
COM port number that is not currently in use (you
can see the ports in use in the Device Manager
Window). Select a port that is less than 10.
NOTE: Windows ® will assign a port number to every device
that has ever been installed on your computer. So if
there are no available ports below 10, choose a port
number less than 10 for a device listed that you know
you are not currently using.
6. Once you select the correct COM port number, click
<OK> and close any windows opened in the process
of changing the port number. Make note of this
number because you will need it when setting up
Prism.
