Hi everybody:

I have been recently using GPSBabel.  It is great!!!.

I need to do 2 things via command line:
1.- After extracting waypoints from a Garmin Etrex, I need to remove or delete those waypoints or all of them from my device.
2.- How do I get the serial number or device ID from command line?

PLEASE HELP!!!!
Thanks in advance,

Regards,

Monic.
