Yeah, I've been kind of busy this week, so I haven't had a chance to look at the patch. btw. Why is is useful to see realtime NMEA strings? If it is to check whether the gps -> empeg connection is working, perhaps having something simple like a virtual flashing led that toggles whenever we've received serial input, and possibly flashes with a brighter color when we've actually been able to interpret this input. That would be more generic as it is applicable to the non-NMEA protocols as well.
