Re: NTP PPS

Paul, Sorry perhaps I am misunderstanding something. Is it possible to get PPS over serial (with a customized serial cable or something) rather than GPIO? If so, would that still need kernel changes? Additionally if NMEA and PPS are then going over serial would it be possible to use a serial <-> USB...
