I don't own the ZED-F9P very long. Therefore I didn't reconfigure the 
u-blox very much. But if I understand your documentation correct it's 
almost always possible to reset the device and bring it into a default 
setup.

The only concern I have, if I change the speed and something goes wrong, 
how to communicate with the device.

/usr/local/sbin/gpsd -G -n -s 38400 /dev/serial0 /dev/pps0

And I see I am several commits behind.
