[time-nuts] nuts about position

The “drops stuff” problem is exactly what I saw trying to run at lower baud rates. 
The port is *not* full of data, there’s plenty of time to get it all out at a lower baud
rate. For some reason (buffers maybe) these modules start dropping data *way*
earlier than you would think they should.
