I'm looking for an easy way to get current lat lon, when you've got a
GPS-18 hooked up for NTP.  That is, the GPS receiver is there doing it's
NTP thing, so presumably it knows where it is.

[]
It's not like ntpd or ntpq have some handy switch that says "display
current lat/lon"  (which makes sense, because NTP is fundamentally time
source agnostic).

All of this with Windows 7.

=========================================

IIRC, enabling clockstats will echo the GPS sentences received by NTP in the 
stats file.  Or, parallel up the RS-232 TX & ground lines (i.e. PC RX line), 
and use a second COM port running VisualGPS (free) to read the data:
