Such records get all the available input but process only matching input. > Non-matching input is silently ignored. That is by design how StreamDevice implements I/O Intr. That all makes sense.
SCAN=I/O Intr checks everything but only reacts on match.
Anything else is assumed to be meant for some other record and thus ignored.
Maybe the issue could be avoided by changing the message from
error .. does not accept input 'MONITOR'
to something like
info .. value 'MONITOR' ignored because outside of expected values.
?
Cheers,
