I just bought a few cisco routers from ebay (a 2524 and 3620). I'm having a hard time connecting to them so i can configure them. The 3620 has 2 ethernet looking ports on the front, they are not labeled i'm guessing one is the console and the other is aux, can anyone confirm this?

I bought a rolled cable with an serial adapter and connected it to the com1 port on my computer and to the console port on the 2524 (and both ports on the 3620) but cant get it to connect. Here are the settings i'm using in hyperterminal:
Bits per second: 9600
data bits: 8
parity: none
stop bits: 1
flow control: none

I've also tried changing it to com2 to see if that was it. Anyone know why i cant connect? I guess the routers could be dead but i was guaranteed that they would not be.
