I wonder if the problem is that his cable is wrong, I have been there done
that before ..
If you are using a rolled/standard console cable with a DB25 connector
plugged into the RJ45 end, try a straight through cable (such as an cat5
ethernet) with a DB25 on one end and DB9 on the other end to your serial
port, and see if that works instead.
