Hannuman my friend,
my impression is that the serial is now working but that the GPS is
not "serving NMEA data".
Under XP I have DL a simple GPS shareware sw called expertGPS and with
it seem able to download the waypoint and other static data but cannot
track any "live" data such as position, time or satellite map.
Are you aware of any command, peraphs via minicom, that I can send to
the GPS unit to see some response ???
thank you,

Bob,
I've never had to send commands to a GPS, so I'm not sure how to do
that. Check with the gps manufacturer to see if they have a
programmer's guide. I've always done the output configurations on the
GPS itself. On my garmin, I always set the "Interface" in the menu to
NMEA serial data format with 4800 baud.
Try using M$ hyperterminal or minicom to view the gps stream. Even if
you're indoors without satellite reception, you can still see the gps
stream. You just don't get any good values.
