Responding to: ???'s previous message
In a specifically crafted '485 network, you *might be able* to hear collisions, but you should not rely on this generally.

might be???

I, regularily make things based on collision detection (e.g. J1708, "node separation") and have never had a problem. The etherenet is based on collision detetection and I have not hear of problems.
