[drats_users] Problem sending GPS coordinates

[Joel Barrett]

Check to make sure the Garmin is sending the NMEA data in the correct
format. For example, my Garmin GPSMAP76CSx transmits NMEA 0183 version 3.01
-- I'm not sure exactly what that means but it could mean the difference
between communicating and not, if D-RATS is looking for it in some other
NMEA format. My GPS can also transmit ASCII or in a Garmin proprietary
format. Maybe ASCII would work better? I do not know what the supported
datarate is so I would have to test it to see if it supports sending data at
4800bps.
 
Also, on my GPS, if the USB cable is connected, it will not send serial
data.
 
Last, verify using Device Manager that you truly are connected to Com1.
WinXP has an annoying way of changing the serial ports to something
different, especially if you are using a USB-to-serial converter cable and
most laptops these days don't have physical serial ports any more.

I hooked up my external Garmin GPS device to COM1. I set the baud rate to
4800 within D-rats and on the COM port.
I selected the button to: Update position from external GPS. I also
confirmed that the Garmin is set NMEA
 input/output at 4800.
 
I setup a QST, type 'GPS', but no GPS data is being transmitted.  I looked
at the Map function and it shows my
location as 0.0000 0.0000.
 
Any ideas why its not working?
