Harlan, Just to report back: - I added the options PPS_SYNC and recompiled the kernel. - I followed the instructions at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html using the "traditional" procedure 1. - I didn't appear to need to add the lines to /etc/devfs.conf - I had already added the following line to /etc/rc.local : ln -s /dev/cuaa0 /dev/gps1 I've included all this information in: http://www.david-taylor.myby.co.uk/ntp/FreeBSD-GPS-PPS.htm The current status can be seen here: http://www.david-taylor.myby.co.uk/mrtg/daily_ntp.html Thanks for your help.
