I have an rj45-rj45 rollover cable connected to an rj45-db9f straight through adapter which is then connected to a db9 serial cable. I can't get a console connection to work in either PuTTY or Teraterm. The session begins but I just have a blank screen with a cursor in the upper left and I can't input anything. I have seen crossover rj45-db9 adapters and was wondering if this is what I need or whether it seems I have a bad connection somewhere.

Are the setting correct on the console session?
Should look like this:
Bits per sec : 9600
Data bits : 8
Parity : none
Stop bits : 1
Flow control : none

I was able to get it working by switching out my rollover cable with a standard straight-through ethernet cable. I'm not quite sure why this works. I just recently obtained my CCNA and I was under the impression a rollover cable was required.

The default Cisco console cable that comes with the device is rollover. You probably are using a straight-through Ethernet cable, but your adapter is rolled

Hello,
Seems like you have nailed it. You do need a proper db9-RJ45 converter for
this to work.

Huh, my adapter is supposed to be straight through. I used an extra db9 cable that came with a UPS I installed yesterday...might this be the cause? I have a sabrent DB9 to USB cable on order so the cabling I had hoped to work was: RJ45 rolled ->RJ45-DB9f straight through adapter ->DB9m to USB serial. Thanks for everyone's help!
