is the "master" "special" in any way?
Could we, for the sake of an example, have two peers interconnected (Q.B), say one at my house and one at my neighbors. And if EITHER detected something amiss...
could there be three peers on the LAN, not just two
Is it able to endure such an event without problems? Without harm to the electronics?
Can the sending device "see" that a collision is taking place?
RS-485 might be just the wheel that I don't need to re-invent!
Then the master controls who talks when (like a teacher in a classroom).
You were never a teacher, were you?
No I wasn't.
Are you sure, you do good write ups.
