    "yes it is rs232"

    How do you know that?

    I mean, how are you certain that it is specifically the RS232 signals that are causing the interference?
    What tests have you done to confirm it?

    "i use keil for the rs232"

    No, you use Keil for loading & reading SBUF.
    Interference between physical signals is entirely a hardware issue - nothing to do with your software development tools!
