I believe once you write something into the serial buffer SBUF it will get transmitted serially within no time (shifting bit by bit to serial pin). Hence no data exist in the SBUF after data transmission completes. Hence it is not possible to read back the same data from the SBUF to a port. (value = SBUF; //not possible)
