[PIC] struct at overrun error and framing error in USART PIC18F4550

[Harshal Dalal]

I'm trying to communicate PIC18F4550 with biomed module. I'm very new to embeded My Module send a packet of 5 byte information continuously at 4800 baud, 1 stop, ODD parity. I've set my baud rate perfectly BRGH=1, BRG16=1. my main is

void main()
{

INTCON=0xC0;
RCSTA=0x80;
TXSTA=0x24;
BAUDCON=0x08;
PIE1bits.RCIE=1;
IPR1bits.RCIP=1;
SPBRGH=0x09;
SPBRG=0xC3;
RCSTAbits.CREN=1;
}

my isr is as

void uart_isr(void)
{ if(PIR1bits.RCIF=1)

for(i=0;i<32;i++)
    {
        PORTD=RCREG;
  if(RCSTAbits.OERR) 
    { PORTBbits.RB6=~PORTBbits.RB6;
      do{ 
        temp = RCREG; 
        temp = RCREG; 
        temp = RCREG; 
        RCSTAbits.CREN = 0; 
        RCSTAbits.CREN = 1; 
      }while(RCSTAbits.OERR); 
} 

        PORTD=PORTD-32;
        buff[i]=PORTD;
        myMsDelay(15);

    }   
} }

i'm getting lots of overrun. please suggest me some method to stop these error
THANK YOU
