Component serial port for delphi 10.2

Hello:

I want to know if it is necessary to have a third party component or is already included in the new Delphi 10.2 Tokyo. I want to turn on and off a Led with Arduino controlling the serial port.

You can download the free version Delphi Edition Starter. https://www.embarcadero.com/products/delphi/starter/promotional-download

Some information is welcome.

Greetings.
