That's an SPI-connected UART - which was number 5 on Jan's List:

Options are:
- get a 2-UART derivative plus some of the solutions below
- switch the 1 internal UART (if data are not simultaneous)
- soft UART if not too high speed and you know exactly what you do
- use parallel interfaced external UART
- use SPI/I2C interfaced external UART
- use a "slave micro" interfaced via I2C/SPI

      Yes , you can build your own software port.            01/01/70 00:00

      No 1 on Jan's List!            01/01/70 00:00      
      no problem in using 805x            01/01/70 00:00      
         do so, but first ...            01/01/70 00:00      
            I\'d say...            01/01/70 00:00

                  makes little sense ...            01/01/70 00:00      
                  No 6 on Jan's List - Why PIC?            01/01/70 00:00      
                     makes little sense ...            01/01/70 00:00      
                        1) why different architecture            01/01/70 00:00      
                        Sense            01/01/70 00:00

                                    Fair point - so back to OP            01/01/70 00:00      
         Maybe one uArt is enough...            01/01/70 00:00      
   use Atmels            01/01/70 00:00      
      why use Atmel?            01/01/70 00:00      
         Maybe other architecture            01/01/70 00:00      
            why on earth do that            01/01/70 00:00      
               Don't let the pot call the kettle black ...            01/01/70 00:00      
                  I do not "call the kettle black" except..            01/01/70 00:00      
                     Noted            01/01/70 00:00      
                        I appreciate that Andy            01/01/70 00:00

                              you must be getting into the Christmas spirit            01/01/70 00:00      
               it's quite easy            01/01/70 00:00      
                  yechhh ... ATMEL (eewwww...)            01/01/70 00:00      
                  8051 -> AVR: not easy !!!            01/01/70 00:00      
                     good discussion            01/01/70 00:00      
                        How can you do this            01/01/70 00:00      
                           hand shaking            01/01/70 00:00      
                              no need of handshaking signals            01/01/70 00:00      
                                 you are right            01/01/70 00:00      
                              Not necessarily            01/01/70 00:00

         it all depends on what he can both get and afford            01/01/70 00:00      
            The architecture doesn't really matter            01/01/70 00:00      
               architectures            01/01/70 00:00      
                  There are many ways of defining "best"            01/01/70 00:00
