[Hamlib-developer] Where does the data for certain lists come from?

[Richard E. <DO...@ho...>]

Hi everyone,

I've been exploring some list commands and I'm wondering where exactly 
the information returned by these commands originates.

Currently, I retrieve all necessary details using the --caps-dump 
command, which works fine. However, it would be great if I could use for 
example get_modes and  get_vfo_list instead. My main question is: are 
these lists generated based on data from the backend (e.g., the 
Raspberry Pi), or are they fetched directly from the connected radio 
each time the command is issued?

The distinction is important, since not all radios are capable of 
reporting their supported modes or VFO combinations. If the radio is 
queried every time, this would make the commands less reliable across 
diverse hardware.

Additionally, is there any way to generate these lists dynamically 
depending on the currently selected VFO? For instance, We've come across 
radios where for example VFOA supports FM, AM, and Digital, but VFOB 
supports only FM and Digital. It would be very useful if the command 
could reflect these distinctions based on actual capabilities.

Thanks a lot in advance!
