Setup for Linux Shell Commands

You can communicate with the FX30 using Legato shell commands. Before
beginning, install a Linux terminal application such as minicom or microcom.
To connect to the USB port on the Linux shell:
1. Connect the USB port on the FX30 to the computer.
In Linux, the AT command port and NMEA port are USB serial devices
located at /dev/ttyUSBx where x is the serial device number in the order it was
connected. X depends on the number of USB serial devices you have con-
nected.
2. Connect an SSH client root@192.168.2.2
