What is the full detection message, including the version number?

Is the "hub" a switch or repeater?  I'm guessing a repeater, but please
be specific about this when reporting collision problems.

How many transmitted packets?

Note that the Tulip chip reports all contention events, up to 15 per
packet, while many older designs report only "had at least one collision this

No, there would be zero reported collisions if this machine were in full
duplex mode.  If some other machine is incorrectly set to full duplex,
you would encounter many addition normal collisions as well as
out-of-window errors.

Try version 0.93
