The right answer is probably:
1) configure protocol (NMEA/TSIP/whatever) in config.ini. I sent Jan that patch a few hours ago and he integrated it.
2) configure things which can be turned on safely inline with proprietary sentences regardless. Again, we dealt with the Oncore last night and Jan has the patch.
3) for receivers which can be "set once" have a menu item to "initialize foo receiver". This would cover the SVee6/SVee8. I guess I'll probably do this for 0.12, unless 0.11 comes later than I expect.
4) for receivers which need to be set each time and speak NMEA (e.g. not the Earthmate, and not the Tripmate, since we know how to deal with that) deal as it comes up. We don't know of any of these yet anyway.
