QtVlm VLM parameters
There are 7 tabs of parameters (apply to all boats):
In the tab File/Directory, you can specify where the grib file will be saved after download. In this case the program will not ask where to save the file.
To emulate a GPS, you must enter a valid COM port (the same as the one used by the receiving program), and a delay for sending the data
A User agent is useful when for instance connecting to VLM with a mobile phone as a modem, and the provider does not allow anything but the mobile interface.
