Installation
There’s an interface 8 in the output which is bound to USB driver qmi_wwan. It is the interface that does the real
network data transmission for this modem. It is attached to an Ethernet mode interface wwan in FortiOS.

Interfaces 0/2/3 for this specific modem are DM/GPS/Modem ports. The DM port is reserved for low-level debugging
purpose; the GPS port outputs location-related information; the Modem port is also known as the AT Command
Interface, to which you can issue AT commands for status and debugging purpose.

The following command displays the modem data interface. The interface seems to be already connected and it has got
an IP address. If you see no output, then something must be wrong with this modem.

The DM port is an industrial standard interface. Write a logging filter in a special format, and it will start to output device
management logging messages. The DM log is very helpful for the modem vendor to diagnose low-level issues. DM
port logging support is not provided in the released version of FortiOS images. The DM log message output might affect
the performance of FortiOS. We will discuss how to obtain a DM log with the help of a debug version of FortiOS image
later.
The DM port (after filter injection) and the GPS port are read-only.
If the device is at a location without good GPS signal reception, the location information can’t be retrieved. The internal
GPS daemon, if enabled, polls NMEA messages from the port continuously. With the GPS daemon disabled, you can
