Ive searched around a bit and cant find an answer, perhaps because there isnt one. Is there any way I can set ntpd to expect a $GPRMC string every 2 seconds, which is the frequency at which the GPS12 transmits them? Alternatively, does anyone know how to make the GPS12 transmit a $GPRMC string every second? If there is a better place I can post this, please let me know. Thanks, Tom
