Hi Vasile, Yes, that progy does the miracle. :D In my case, only TX needed to be inverted in FTDI configuration.
@Rob, My mistake (and sorry to Kiste) saying it was Vasile who spoted that OSC misconfigurations first time. *In fact it was Kiste* who spoted that mistake and helped me to solve that baud rate issue. Anyways, thank you all. This community rocks big time. Cheers, Filipe Santos.
