Alarm Relay Output Application

Programming Interface

This appendix provides a sample program that illustrates how to get/set the status of the alarms. The application can use LOMIOCALSTATE ioctl to obtain the status of each alarm and LOMIOCALCTL ioctl to set them individually. For more details on the Alarm Indicators, refer to the Netra 440 Server Service Manual (817-3883-xx).
