Re: [Hamlib-developer] YAESU: xxxxx_get_update_data()

[<wu...@pi...>]

Darren,

Thanks for info!

yep... looks like a major software engineering stuff-up from YAESU. It 
would have been trivial to implement selective calls for such purpose.

This means that I have to read the complete update-data array of 1492
bytes... :(
