This signal indicates that the port is no longer accessible. Unlike a udev port removal event, this indication may happen even if the port is still exposed by the system. It is designed to detect protocol proxy crashes, and so when such event is detected by the modem, a full reprobe of the device will be done to start from scratch the protocol management operations.
