@Ryan12,
possibly this is first time you use serial interface in processing,
and you started with a
arduino ( firmata )
example.
this ONLY can work if the arduino is loaded with the firmata sketch.
when you say that you see the data incoming
in the arduino IDE monitor ( terminal emulator )
you not have firmata loaded to arduino,
you have your own code sending data continuously by serial.println()
in that case you only use in processing the
import processing.serial.*;
and how to setup see for a example for that library (only )

also can you tell us where the
come from?
it is good practice to first print the port list.
