The <R+> means that the module is transitioning the communications line to a
transmit state.
All characters shown in <> brackets are characters being sent out by the module.
The <R-> shows when the module is done transmitting data, and is now ready to

After taking a minute or two of traffic capture, you will now want to stop the "Data
Analyzer". To do so, press the 'S' key, and you will then see the scrolling of the
