#include <16F887.h>
#fuses NOMCLR, INTRC_IO, NOBROWNOUT, NOLVP
#use delay(clock = 8MHz)
#use rs232(UART1, baud = 9600)

const char message[] = "PIC16F887 microcontroller UART example" ;
int8 i = 0, j;
void main(){
  setup_oscillator(OSC_8MHZ);                    // Set internal oscillator to 8MHz
  delay_ms(2000);                                // Wait 2 seconds
  // Print text
  printf("Hello world!");
  // Print list of characters
  printf("\n\r");                                // Start new line
  while(message[i] != '\0'){
    putc(message[i]);                            // Write character
    delay_ms(100);                               // Wait 100 ms
    i++;                                         // Increment i
  }
  // Print numbers
  printf("\n\r");                                // Start new line
  for(i = 0; i < 21; i++){
    printf("%u\n\r", i);                         // Print i and start new line
    delay_ms(500);
  }
  // Receive and send data via UART
  while(TRUE){
    if(kbhit()){                                 // If a character available
      j = getc();                                // UART read
      putc(j);                                   // Send it back
    }
  }
}

After I build the circuit and burned the HEX file into the PIC16F887 using PICkit 3 programmer, I got a result as shown in this video (using CCS C Compiler IDE Serial Monitor tool):
