Objet : Re: asynUInt32Digital write callback function not called

Having SCAN="I/O Intr" is somewhat unusual for output records.   Are you sure this is what you want?  I ask this because it is the reason that you don't see the record process when you write to it -- 'process on write' occurs only if SCAN="Passive".
