To be clear about the yes/no, let me tell you an example from yesterday:

- We are building an embedded system, which has a data interface, which is not working properly (nothing is being received). We have to take care of the emitter, other team the receiver.

- My question: after lunch you are going to see with the oscilloscope of there is activity in the interfaces lines?

- Answer: No need, the registers in the ASIC indicate transmission is ok.

- 2nd question: but maybe there is a malfunction in the ASIC, and still there is no transmission, so we should test.

- Reply: The other team will check if there is reception or no.

- 3rd question: but the other team confirmed there is no reception, even with oscilloscope... could you test?

- Reply: what test do you want me to do?

- Me: measure with oscilloscope

- Reply: what for?

- Me: To confirm the transmission

- Reply: I dont follow...

- Me: here I start to ask, step by step:

    - We have a problem of transmission, right?

    - Yes!

    - Registers in ASIC indicate no problem, right?

    - Yes.

    - The other team reported still there is nothing in the receiver, right?

    - Yes.

    - So it would be useful to physically test with oscilloscope if that is being send, don't you think?

    - Yes, sure!

    - So you are going to do it, later, after lunch?

    - Yes, no problem.

Yes, that guy has a PhD. Is my problem that I'm asking yes/no questions?
