USB modem port
Each USB modem has a specific dial-out ttyusb port. This will be indicated with the documentation for your modem. To enable the correct USB port, use the CLI commands:
config system modem
set wireless-port {ttyusb0 | ttyusb1 | ttyusb2}
end
To test the port, use the diagnose command:
diagnose sys modem com /ttyusb1
The ttyusb1 will be the value of your USB port selected. The response will be:
Serial port: /dev/ttyusb1
Press Ctrl+W to exit.
If the port does not respond the output will be:
Can not open modem device ‘/dev/ttyusb1’ : Broken pipe
