Orolia WR-Z16 - Connecting on Linux (Ubuntu 18.04 LTS); Logging from UART

Note: DHCP IP address: The assigned IP should persist between
device reboots, as it will ask for the same address after every
bootup.
3.
To use a manual network configuration from UART:
Connect the device using UART (see "Logging from the UART" on
page20).
Follow the steps described in network configuration from CLI (see "Network
configuration from CLI" on page37).
Reboot the device.
Connect eth0 or eth1 (according to the user network configuration).

3.2.4.1 Logging from UART
To connect to the device terminal via UART, use the RJ45-RS232(m) and RS232(f) USB
to connect to the UART management port, in the front panel of the WR-Z16 as shown in
the "Front panel" on page8 Hardware section.
The recommended software to manage UART connections on Linux is picocom, which
you should be able to install just by running with super user privileges:
sudo apt install picocom
Once installed, the command to establish the connection with picocom is similar to:
picocom –b 115200 /dev/ttyUSB<X>
where ttyUSB<x> corresponds to the instance of the USB-UART driver. In most of the
case, it will be ttyUSB0 (e.g., only one USB-UART cable connected to the PC) and the
expected output is as follows
$ sudo picocom -b 115200 /dev/ttyUSB0
Calling 'sudo /usr/bin/picocom -b 115200 /dev/ttyUSB0 -b 115200'
Exiting Ctrl+A, then Ctrl+X
picocom v2.2
port is : /dev/ttyUSB0
lowcontrol : none
baudrate is : 115200
parity is : none
databits are : 8
