[Gpsbabel-code] What am I doing wrong? Coversion problems between mapsource and gpsdrive

[Martin T. <ma...@ma...>]

Having learned yesterday that I cannot store data from my eTrex Legend 
in a garmin format, I tried downloading
from the gps and saving it as mapsource and later converting to 
gpsdrive. Should work, right?
Here's the commands:

gpsbabel -t -i garmin -f /dev/ttyS0 -o mapsource -F garmin.mps  // 
download track data from a garmin and output to garmin.mps as mapsource
gpsbabel -i mapsource -f garmin.mps -o gpsdrive -F 2garmin.gpsd  //  
open a mapsource file and write out as gpsdrive

Here's the problem, the format is not gpsdrive. Here's a few lines from 
2garmin.gpsd:

RPT001 33.09101 -96.63538
RPT002 33.09144 -96.63572
RPT003 33.09131 -96.63542
RPT004 33.09136 -96.63551
The co-ords are right but where is RPT001 coming from, or more to the 
point, what is it doing in a gpsdrive format file?
Gpsdrive will not load the file.

If I download the data directly as gpsdrive, like this:
gpsbabel -t -i garmin -f /dev/ttyS0 -o gpsdrive -F garmin.gpsd

then the top of the file looks like this:
 33.09101 -96.63538
 33.09144 -96.63572
 33.09131 -96.63542
Gpsdrive will load the file.

Any thoughts?
