Here is a repost of a message originally written by Brian Dennis with
configs. It works, --the one on Cisco's web page does not. One problem is
that it only makes the call in one direction, so it's not good for callback
practice but everything else works.
Just a regular console cable from Aux to Aux.

Below is a working config for AUX-to-AUX dialup using a rollover cable. R1
can call R3 using these configs.
