It is available in microchip site itself.... once again read the datasheet of PIC16f877a

// U A S R T   C O N F I G
   TXSTA   = 0b00100000;
   SPBRG   = 0x33;         // Baud = 1200
   RCSTA   = 0x80;         // Enable serial port and dis RX

void WriteUSART( unsigned char data )
{
   while(!TXIF);         // Wait till reg is empty
   TXREG = data;
}

// For RX
// U A S R T   C O N F I G
   TXSTA   = 0b00000000;   // Tx Disables
   SPBRG   = 0x33;         // Baud = 1200
   RCSTA   = 0x90;         // Enable serial port and Rx

// Read RCREG if RXIF is set
