as nmea2000 seems to be O.K. at the moment, i do not want to stop the release.

As the firmware bug, that triggers to problem below is fixed, i had to setup a 
test to reproduce the problem.
I come with the problem again, as it think, that it may be related to the OS X 

 I hope, that it works with my serial player and two  ftdi adapters connected, 
on spitting out a NMEA0183 datastream with a few errors and a fixed baudrate, 
the other trying to read the datastream with gpsd/gpsmon.

I don't have a test load that reproduces this behavior, or I'd have fixed it.

Can you bisect to identify when this began to happen?
