@bart Hold your horses before you destroy your Pixle...
RS-232 is -12V +12V line voltage and that is way beyond what any processor can handle except you put som drivers/receivers in between.
I could read nothing specific about the RS-232 in Novatel Flexpack6 specs that would say different, also because the connectors look like classic RS-232 9 pin (25 pin) D-connector.
I expect that you have to use a level converter / adapter with a chip like the MAX3232 - Datasheet.
This is for full control. To get started with just receiving date, you may get away with some simpler setup... which of course would need some bread boarding...
