Questions

* Is the bytestuffed format solid enough with todays firmware? (1.2.26+)

** Is bytestuffed format required for GPS + normal ECU logging parameters?

Use cases

* It would be useful to be able to have the option of using either the 1st or 2nd serial port for NMEA communication.

** NMEA GPS module connected to 1st port, datalogging to MMC

** Laptop, Android or AIM display connected to 1st port, NMEA GPS module to 2nd, datalogging through 1st

* Using 1st port for NMEA requires communication to be robust enough.

** AIM, Trigger frame format and NMEA on the same port.

Hardware

* A couple of these has been ordered : GlobalSat BR355-S4 SiRF Star iV GPS module

** http://www.usglobalsat.com/p-689-br-355-s4.aspx

** PS/2 connector for GND, VCC+, RX, TX

** Weatherproof
