When
a device is added, you have the option of changing the name of the device, and
whether the device is enabled or not. If the device is not enabled, it
won't function, however you can enable it again later. The exception to
this is with U4x1 devices. These devices are automatically
detected, so they are automatically enabled when they are attached, and
automatically disabled when they are not attached.
If the device is a CM11A or other device that is hooked to a serial port, the Port Setup button will be visible. This is where you can change the COM port to use, and also to change the settings for that port.
When you click OK, the window will close and your changes will be accepted. If you click Cancel, the window will close and your changes will be discarded.
