I'm very new to Linux environment and need some help.
I have pc that runs on Ubuntu 22.04. I would like to connect to another system that has a specific IP address, through serial port. How can I achieve this.

The serial port usage is very old and rare nowadays... But it is possible. There was a PPP (well, still is) but I am not sure it exists in the modern distributions.
