*    Function Name:  SlaveputsI2C2
*    Description:    This routine is used to write out a string to the 
*                    I2C bus.If write collision occurs,-3 is sent.If 
*                    string is written and null char reached, 0 is returned.                 
*    Parameters:     unsigned char * : wrptr
