Re: [Gpsbabel-misc] Help connecting to a Garmin GPS II Plus

[Jack F. <jcf...@me...>]

Since the command line is working I'm happy to use that instead of using 
the GUI. So, you don't need to waste your time looking at it any longer. 
I have been exploring the different command line options and I can now 
save the read GPS data to two different formats. That's really cool. I 
consider my problem solved.

Thanks,

Jack
