                                       Yes, I think I've done this correctly            01/01/70 00:00

      I have problem with serial port 1 on ds89c450 (www.maxim-ic            01/01/70 00:00      
         MUCH better description needed            01/01/70 00:00

               Which register bank are you using?            01/01/70 00:00
