This section describes how to set up the EVK-L2 for browsing the internet with a Linux operating system on a PC
connected with the EVK-L2 over the USB interface of the TOBY-L2 series module. Follow the board setup
instructions described in section 1.8 (except the Windows OS settings) to provide communication via the USB
interface of the TOBY-L2 module. Use minicom or a similar program to send AT commands to the TOBY-L2
module.

Identify the CDC-ACM connected to the Linux OS (
ls /dev/ttyACM*
) and then launch minicom to use
this port. In the example below the port is
ttyACM0.
