The CommPortClearErrors() function looks at the overrun error and framing error bits and clears the error if one or both have occurred.

Add this function to the serial.c file and also don't forget to add the function prototype in the serial.h file.

We just need one more function in order to complete the Hello World program.

/*
// function: CommPortClearErrors( void )
// description: This function clears the
//                          overrun or framing errors.

   if( OERR )
   {
      TXEN=0;
      TXEN=1;
      CREN=0;
      CREN=1;
   }
   if( FERR )
   {
      dummy=RCREG;
      TXEN=0;
      TXEN=1;
   }
