I guess this is actually the USB-serial bridge to the GPS, and Solaris
can't really see the GPS behind it.  Linux does somewhat better,
recognizing the device as a Pharos, but I'd really sooner have my
stratum0 on my NTP server, not on one of its clients.

Of course, I suppose I could always set up the GPS on my workstation,
which would make the workstation's ntpd stratum1, and babylon4's (aka
ntp.babcom.com) stratum2...
