The following guide will walk you through on setting up USB Serial Console Cable on a Linux via command line.
First of all, make sure you have a program called Minicom installed.
I will be using Ubuntu flavored Operating System for demonstration purposes.
apt-get install minicom
Then you need to connect the USB Serial adapter and find out which serial port is it connected to.
dmesg | grep USB
You will see something similar to this output.
[ 6.804403] usb 1-1.3: pl2303 converter now attached to ttyUSB0
Make sure you
chmod 777 /dev/ttyUSB0 so minicom will allow you to save the config.
Open up minicom by running the command
minicom -s and select Serial port setup
Reflect the output you saw from dmesg and set it to the Serial Device by pressing AE > C
A – Serial Device : /dev/ttyUSB0
E – Bps/Par/Bits : 9600 8N1
Please see the following screenshot for more info.
Then Save setup as dfl then exit.
You should be able to login via the console port like the following…

If you wish to exit Minicom, use the command Ctrl A then Z then X.
