This is not a Proteus forum. It's the CCS compiler forum.
Do you have the CCS compiler ?

To find Proteus schematics for CCS projects, go to Google Images:
http://images.google.com
Search for this:

proteus RS232 CCS

or just this:

proteus RS232

You will see several schematics.

Here is a simple test program for the PIC's serial port.
It sends "Start:" to the serial terminal. Then it reads
characters that are typed into the terminal, and sends
them back to the terminal.
Code:

#include <16F877.H>
#fuses XT, NOWDT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

//====================================
void main()
{
char c;

printf("Start: ");

while(1)
  {
   c = getc();
   putc(c);
  }

}
