I'm afraid I am not at all familiar with the Blackfin. I would suggest reading the manual section on the SPORT. Don't bother with the TDM section as that is more complicated than what you want. Also, be sure to post these questions to the list also since there are many others more knowledgeable than me. Are you sure the Seimens modem is not and asynchronous
