I am struggling with a rather simple task. Here is the problem:

I would like my M3 CD12 to send the inport status out on the serial port every time the status of the inport changes. I know that you can send a read command to the M3 and then receive the inport status but I don't want to use that kind of polling method.

Does somebody know how to achive this behavior?

The reason why I need it is because I have an application that needs to react on changes and I don't want to do a lot of work on unnecessary polling.

Any help would be really appreciated.
