I agree that collision cannot happen on a serial interface. I read some where not quite sure where might have been caslow, but if you do increment collisions on a serial interface you are looking at a software problem. Hope this helps. Lori CCNP

Perhaps, I'm wrong, but as Brian said, collisions are a side effect of half-duplex transmissions where the two ends try to transmit at the same time. I can't think of any other specification besides ethernet where collisions can happen. Mike W.
