Have you set the monitor window to 2400 baud in the lower right corner?
Put a Serial.println("Some text"); after your Serial.begin. Does it appear on the monitor?

Are you using the right sort of tags, that is EM41000 types.
although the RFID led remains Red the entire time
Quotealthough the RFID led remains Red the entire timeDoes that include when a token is presented?If so all I can think is that the reader is not working.Have you got a scope so you can check signals?
When you disable the reader does the LED turn green?
Did you not understand that?In order to find out what is wrong you need to test things. So you need to write a sketch that toggles the enable line like a flashing LED.Then you need to see if you are getting anything from the serial port. To do this I would suggest you power the arduino sepratly, not from the USB and blink an LED every time you see any character from the serial port. By having the USB disconnected you remove the problem of two signals fighting to control the RX line. Does your arduino have a 1K seriese resistor. I ask because it is only an arduino clone, not a real one and it might be the issue.Finally you could try recieving data on another pin using the new software serial library.
