MegunoLink includes two visualizers for monitoring data coming in the serial port and showing it in a text buffer:

The Raw Serial Monitor is like the Serial Monitor built-into the Arduino IDE. It shows all of the data received from your Arduino.

The Message Monitor visualizer is more selective. It looks for specially tagged data and only shows that. This lets you easily separate messages for logging or a comma-separated value stream from all the other data your Arduino is sending. If you use the Arduino’s serial port for sending debug and diagnostic messages, as well as plot and commands, the Message Monitor is a easy way to get a clean serial stream.
