Does anyone know my problem, i'm use the Tx Rx (EUSART) function with 
the code list below

        CloseUSART();
        OpenUSART (USART_TX_INT_ON &
                    USART_RX_INT_ON &
                    USART_ASYNCH_MODE &
                    USART_EIGHT_BIT &
                    USART_CONT_RX &
                    USART_BRGH_HIGH, 25);     //good result is 50 on 
57600 baudrate, 25 --> 115200

        baudUSART (BAUD_IDLE_CLK_LOW &
                    BAUD_8_BIT_RATE &
                    BAUD_WAKEUP_OFF &
                    BAUD_AUTO_OFF);
        while (BusyUSART());
        WriteUSART    (  0x01 );

        while (!DataRdyUSART());
        getsUSART (usart_input_buffer,1);

        output_buffer[0] = usart_input_buffer[0];

I'm use the above code in old version PIC18F4550 (i'm buying the 
PIC18F4550 one year ago),  is normal and good function for the TX and RX 
pin. But now I'm buying the several new PIC18F4550 (I'm buying the 
PIC18F4550 one last day) the RX pin is not function, does anyone can 
suggest me what can i do!!! maybe if in this forum the enginer from 
microchip is available, can give me a suggestion? Now i'm very confused 
with this insident???
