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.
