bpm_enable_tbt_trigger_c

	status.i4.v = bpm_enable_tbt_trigger_c(enable.i4.v [,house.i1a.r]
					       [enable_info.g.v])

	This routine enables or disables BPM turn by turn triggering
	for the machine last requested by a call to bpm_machine_c.

	enable		trigger enable flag
			(TRUE -> enable triggering,
			 FALSE -> disable triggering)
	[house]		name of house to control (If a value of NULL is
			passed for this argument, all turn by turn timers
			for the current machine will be affected.)
			(default is NULL)
	[enable_info]	additional information for enabling/disabling
			(BPM_TEVATRON -> structure of type
					 BPM_TEVATRON_TBT_TRIGGER_INFO,
			 BPM_MAIN_INJECTOR -> structure of type
					      BPM_MI_TBT_TRIGGER_INFO,
			 BPM_RECYCLER -> structure of type
					 BPM_RECYCLER_TBT_TRIGGER_INFO)
			(default is NULL)

	This function returns ACNET status values as follows:
