Inputting GPS NMEA data into micro USB port

[Charlie1220]

I'm new to this forum, so forgive me if this subject has already been discussed. I am government contractor working for the Navy on their GPS systems, and would like to use my Motrola Droid 3 to view NMEA GPS data at various places throughout the various GPS data lines. Is there such an app available, and can the micro USB port be configured to accept RS-422 or RS-232 data once it's converted over to USB?
