5-12
3. NPort Windows Driver Manager will list each available serial port and will automatically assign a new
COM port to each one. The new COM port will not be accessible by the host system until it has been
activated in NPort Windows Driver Manager. Activating a mapped COM port saves the information in the
host system registry and makes the COM port available for use. Click Yes to activate the COM port(s) at
this time; click No to activate the COM port(s) later.
4. Activated COM ports will be listed in black; COM ports that have not been activated will be listed in blue.
Once a COM port has been activated, the host computer will be able to communicate with the new COM
port as if it were physically attached. Since the COM mappings are stored in the host system registry,
they will still be in effect if the PC is restarted or if Windows Driver Manager is closed.
