What type of GPS device do you have? Look at the NMEA driver, #20 If you can setup your box to send $GPRMC messages every second or few, the rest should be easy. The $GPGLL messages do have a time time stamp. It should work if you say something like "ttl 4" on your server line. (The documentation needs updating.) The PPS signal is a separate wire, usually connected to DCD, maybe requiring some external level shifting. -- The suespammers.org mail server is located in California. So are all my other mailboxes.
