First, you can try opening a bug report using the "refclock - palisade" component. Next, you could try using -dd to see what sort of debug output you get, and mess around in refclock_trimble.c . If all else fails, there are a number of decent and inexpensive USB GPS pucks out there that might do well for you, instead. -- Harlan Stenn <st...@ntp.org> http://networktimefoundation.org - be a member! _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
