Hi I0hannes,
thanks for your reply. you're definitely right, in fact that's how I wrote my patch, I probably kept my question to vague. it's not a problem, I can see several workarounds for that, so it's fine, it's more about better understanding what's going on under the hood. I always use [t] to be sure that the oder of operation is correct, but I also know that there's a "rule" about the order of connection. so my question would be, is there any rule behind the [send] and [return] behavior?
cheers,
Mario
