Listening to a Serial Port on Delphi 7

Question

I am trying to write a program that will listen to serial input from an Arduino board connected via usb and send the output to the serial port (COM4). But I do not know how to get input from the serial port in Delphi. I need a program to listen on the port, and whenever an input arrives, it must respond to it. Any suggestions?
