Modem
Configure the serial port used by an attached cellular modem for mobile connectivity.
The Modem page configures the serial port used by an attached cellular modem, if one is present on the device.
Port — the serial port identifier assigned to the modem by the operating system. For example: COM10 on Windows, /dev/ttyUSB0 on Linux.
Click Save to apply. The modem service uses this port for cellular connectivity — for example to reach a Supervisor or myACCESS cloud service when no Ethernet connection is available.
