PIC HANGS with SERIN and Timeout?

[skimask]

I have taken a look at the idling thing, but don't understand it.
I have also tried both SERIN and SERIN2 with timeout (10 milliseconds)

Well, I've never had the idling problem myself, so I can't really comment.
About all I can suggest is to read the threads again (there's one by Melanie that's especially long and useful) and you're answer will be in there somewhere.
If I would have to guess, I would say that your input pin is just sitting there at a low logic level. If it is, pull it high and see if the timeout works.
If it's sitting high, pull it low and see if the timeout works.
