AFAIK, a loopback means that the Tx path is wired to the Rx path, so that
whatever is sent comes back immediately. The fact that you have them

an external device.

Uh, what is a "remote loopback" ?

You can always register for free as a developer on the 3Com site and have
access to the documentation in PDF format. That's all I have, anyway.
