Correct - no JSON is ever received.  Also, cgps starts, draws the boxes, and 
the quits.  Does cgps use JSON to talk with gpsd?

I’m seeing inconsistencies when testing further.  Sometimes gpsd hunts & never 
is able to speak with the GPS (auto-bauding fails).  Let’s not spend more time 
troubleshooting with this specific GPS.  Bluetooth serial connections are a 
pain in the rear, and I suspect this is the problem.  Mac OS X drops the 
bluetooth serial connection as soon as the client closes the connection.  I 
suspect it might be resetting the tty settings or expecting certain tty 
settings when re-opening the bluetooth serial connection.

Can anyone recommend a USB GPS receiver?  With PPS would be nice, but is 
optional.  I thought someone on the list had purchased a “lot” of GPS receivers 
and still had some for sale, but don’t remember who.

Thanks,
Frank
