Most modern terminal emulators support VT100 escape sequences. These sequences are special commands that allow you to manipulate various terminal elements, such as color, style, and cursor position. If you're interested in this topic, you can find a detailed explanation here.

The demo below isn’t interactive—it simply showcases how you can format the Serial output.

Live Demo

This can be a very useful example if you want to test the capabilities of your terminal emulator. This clever little example simply tries out every combination of formatting settings so you can see what each one results in.
