How about a serial port spy/monitor program. There are some free ones like:

One very direct way is to find some software to sniff the com port where the

Subject: [time-nuts] GPS-18, Windows, NTP & Lat Lon
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.
If NTP is decoding the GPRMC message, it has the lat/lon in it, so how can I
get that info out (in a command line utility, into a file, or some such)
I don't need millisecond time accuracy.. For now the GPS is just to make sure that the
time is "right".
The GPGGA sentence would also do.
And, I only need the GPS position once within a 30 second interval (it's not
moving, I just want to know 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.
