You don't think SEROUT2 running 20MHz could send enough data to change the default setting in the radio module? Is my syntax correct in how I'd send it? If you think that the serout won't do 19200 then I think I'll just cut my losses and try find another module that just works, the manufacturer did say that I could send it back and they would change it in the factory and send it back to me - however they r on the opposite side of the planet!
