    Is there already a firmware for the pic 12f683 which allows connecting a serial rs232 line instead of the dip-switch ? There is an example of a bitbang

      There is an example of a "bitbang" 9600baud rs232 firmware on the
      microchip page. From experiments with AVR's i know that a rx-only level
      conversion rs232/cmos can be very simple if the firmware is able to read
      an inverted rs232 signal.
