Thanks to both you Marc & Otto. Your comments have helped with a number of questions. I'm currently questioning the power supplied to the Garmin which I will get to tomorrow. For now, I've gone back to my T43 laptop where I have a USB Delorme GPS LT-20. I can now see the sensor as well as NMEA sentences through cu there. Three questions. I'm still not seeing anything appear in /var/log/daemon. How soon should log messages appear? >From the archives, I remember a statement made that without a pulse per second (PPS) signal, a GPS unit would only be able to minimally coordinate the time through ntpd. This statement was also made in reference to a USB unit. Are PPS signals inherent to all GPS units but are lost through an USB interface? Is there something within the NMEA sentence traffic which should tell me that I have a PPS signal? Thanks again for your clarifications.
