Hi everyone,

    "My SBUF was stored with some data"

    No, you cannot "store" data in SBUF!

    When you write to SBUF, you are feeding the UART's transmit buffer;
    When you read from SBUF, you are fetching from the UART's receive buffer;

    So you cannot read-back the data that you wrote to SBUF!

    This is fundamental to the operation of the 8051 hardware - it has nothing specifically to do with 'C', Assembly, or any other programming language.
