	This routine determines whether or not a device's alarm is
	bypassed.  A returned value of TRUE means the device is bypassed.

	device_index	device index of interest
	alarm_type	type of alarm
			(DIO_ANALOG -> analog alarm,
			 DIO_DIGITAL -> digital alarm)
	bypass_state	returned bypass state
			(DIO_ALARM_BYPASSED -> device is bypassed,
			 DIO_ALARM_ENABLED -> device is not bypassed,
			 DIO_INVALID_DATA -> error occurred in reading data)
	[ftd]		Frequency Time Descriptor (FTD)
			(FTD_ONESHOT -> one shot (default),
			 FTD_DEFAULT -> use database default FTD,
			 FTD_1HZ -> 1 Hz request,
			 FTD_EVENT_MASK OR'ed with TCLK event value -> read
			 on TCLK event (event constants are in tclk_events)
			 (can use the macro BUILD_EVENT_FTD(event) or
			  BUILD_EVENT_PLUS_DELAY_FTD(event,delay) in 'macro'))
	[start_block]	starting block to return (starts at 0)
			(default is 0) (maximum is DIO_MAX_ALARM_BLOCKS - 1)
	[max_blocks]	maximum number of blocks to return per device
			(default is 1) (maximum is DIO_MAX_ALARM_BLOCKS)
	[num_blocks]	returned number of blocks returned (default is NULL)

	This function returns ACNET status values as follows:

	OK			success
	otherwise		ACNET format error
