RE: ntp serving.  How exactly does the server sync to information
provided by a GPS receiver?   Does it simply read the RMC string or
equivalent on a serial port
or does it also use the PPS as in interrupt and if the later is
necessary, is that received via an SBC's parallel port bit.    Does
the server then make time information available on request?
