Networking :: Reconfigure Microcom

I hope I have this in the right forum. I need to know how to reconfigure microcom to connect through "eth0". I run dsl-interntet through an ethernet card. I want to be able to use microcom to handle a few touchy details online. I use to be very good in Win95's HyperTerminal & have been told that microcom is the closest I can come to that. I thank everyone for all their time & trouble. Thanks for the help.
