[time-nuts] GPScon running on Raspberry Pi 3b

[Mark Sims]

No, it's not a bug.  It's the way it is intended to work.  Whenever Heather sees a command to open/change the serial port, the currently open port (if any) is closed and the new one is opened.   

Heather lets you change the serial port or read a config file on the fly from the keyboard.   Trying to filter when to ignore or delay opening the port is a needless and potentially error prone complication.   The simple / robust / reliable thing to do is just try and open it whenever / wherever a serial port command is seen.  

Most people with just set up the config file for their default port and never use the command line option or do things like changing the port or loading a config file from the keyboard,  but it can be quite handy if you are playing with lots of devices.
