Use the Parametric search at www.microchip.com, find one with a UART/USART on it, pick and chose which one you want.

during my search on internet i found some one make circuit to do that using pic16f84 and lcd (20*4) but the one who design this circuit place assembely software for the pic but i am not good at all on assembely
Well, email them, maybe they'll share their code...maybe not...
that's the breaks...and without knowing what data is where in the data stream, you may as well be receiving random noise.
