	56K Baud is a bit time of 17 uS. With a 10 bit character, that is an interrupt every 170us. A 11 MHz crystal means that an instruction takes 1.1 or 2.2 uS. That gives you between 75 to 150 instructions per character. That should be enough time to do an interrupt and still have time left over for the main function.

                  10 or 11 bit times?              01/01/70 00:00
                     sometimes              01/01/70 00:00

            that works, this does too (and, in my opinion) is              01/01/70 00:00

                        sure but what does that have to do with it?              01/01/70 00:00

      not quite              01/01/70 00:00
         I shoul have said "in your case..."              01/01/70 00:00
