1.1     01-Jul-02   R. Kuhnen           Added conditional compile for pSOS and 
                                        vxWorks because vxWorks needed different 
                                        value for event define.
1.2     24-Oct-02   R. Kuhnen           Added NO_RTOS conditional compile for TXC_CMD_REPLY_EVENT
