um, yeah.  wasn't Geotracker included with MapInfo in the first place?  i
know i've used it successfully many a time, and it's very simple.  just plug
your GPS into the com port, make sure goetracker recognizes it, then it can
record a route as a polyline (NMEA), at the same time plotting your current
position as an object, and if you set up a table beforehand with the correct
fields, you can plot points as you go which are able to record the data
usually displayed on the GPS (speed, heading, PDOP, altitude, etc.).

i was using this to record bus routes and bus stops, and when i got back in
the office i wanted to watch us drive the route, however the problem is that
with geotracker you can only playback in real-time.  but with the route file
it records the NMEA sentences, including (i think) satellite data and
everything, so i remember once finding a program that could read these files
and play them back as fast as you wish.  i forget where it is, but nowadays
i think it wouldn't be too difficult for me to do make up something like
that myself if i were so inclined.

actually i found the program that will replay the data, but not on a map.
if you use geotracker or whatever to record an NMEA log file, this can open
it and play it back as fast as you want.  check out www.commlinx.com.au.
i'm sure if you look around there'll be a gaggle of programs that will
interface NMEA sentences with mapinfo.  i will probably be looking into this
myself in the next month or two anyway, so i'll let you know what i figure
out.

problem is to read the COM port from mapinfo correctly without freezing 
the machine. doesnt work with mapbasic.

but download
http://www.bluemarblegeo.com/products/geotracker.php?op=download
that does the job with an external dll.
can save routes as mapinfo files as well.

christof
