How to install Minicom on Linux / Ubuntu

Minicom is a text-based serial port communications program. It is used to talk to external RS-232 devices such as mobile phones, routers, and serial console ports.

We can install minicom using below command,

$ sudo apt-get install minicom

Once you install minicom successfully, Connect Serial to USB cable to ubuntu laptop/desktop and type “dmesg” command on terminal as,

$ dmesg
