Thanks, Paul.  For a test code I am not reading the encoder, but incrementing the count with a delay between each increment. Here is a code snipet.  I have also removed the 573's and jumpered straight across.  I am using an extra output line, ra.1, to tell the PC when the lines should be stable to read.  I have seperated my delay into two delays to give time for the outputs to settle

Main    call BitTime1

          setb  ra.1             ; OK for PC to read 

          call BitTime2

          clrb ra.1               ;  Not OK for PC to read

          inc   lowbyte

          jnz   noInc

          inc   highbyte

noInc   mov rb, lowbyte

          mov rc, highbyte

          jmp Main
