The ALARM sounds (if supported by the device) when the record format  
is DISPLAYED--not when it is written. Default behaviour is for writes  
to be deferred until a request for user input occurs. Solutions are:
	1) Force the ALARM record format to the device: FRCDTA DDS keyword
	2) Don't defer writes: DFRWRT(*NO) on CRTDSPF or CHGDSPF
