 		 #159642 - These are NOT RS485
Responding to: ???'s previous message
I said:
In a specifically crafted '485 network, you *might be able* to hear collisions, but you should not rely on this generally.
Erik Malund said:
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.

J1708 and ethernet are NOT RS485.
