I am working on my CCNA and have just received two 2610s and two 2952 switches. I am connecting my laptop to them with a rollover cable and I'm using Hyperterminal (I also tried Putty) as my interface software. The software is setup just like the book says to set it up. I cannot get the IOS's on any of the routers or switches to come up on my computer. I am using Windows XP. Is there something I need to set up on my computer? What am I doing wrong?
