Console connection with putty -issues with response from router


I have bought 1841 router from ebay. When i started my console connection using usb to RJ45 console cable, putty terminal displayed the output as per attached image. First time i didn't able to enter 'Yes/no' input to "Would you like to enter the initial configuration dialog?[yes/no]:". Then i have changed my settings to local echo "force on" from "auto". Then i was able to enter my keyboard input as 'no'.

After that no response from router?.

I am using Windows 10 latest update.

What settings i have to change to make it working?

Please advise me.

(attached my various putty settings fotr your reference)

That 1841 router from ebay was not declare as "Parts only" or "as-is" 'cause if it was, it might be broken. 

You should use default Putty settings unless you have custom keyboard or non-English language enabled on Windows. Settings 8-1-none-none are correct; and your speed 9600 is also correct, otherwise you would not see readable ouptut.

When router loads you should see any errors if there are any.   do you see any?

You can try removing CF flash card from router; restart or boot it; router should go to ROMMON mode. type ? or help to see options; It is also good test to see if router takes your input; then try "set" command to see all settings.

Rommon mode -(image attached as actual)

after my 'enable'input , there is no response from router.



you cannot use "enable" in ROMMON, use ? or type "help" to see commands; There are special commands for ROMMON mode; not regular IOS ones.  I think all routers will take "set" to see a list of configured options (set is standard command in ROMMON).
do "set" and take a snapshot of settings; should be a list of several settings.
Do does router takes your words as your type them now? this is a test of keyboard and putty connection.



I have tried 'set' commands too.(attached screenshot)

But no reply from router for any typed inputs(?,help)

I didn't see any error while router loads.

Looks like some one wiped IOS from the routers flash Card if it boots to ROMMON like that it means it cant find it operating system (IOS) it boots to that think of ROMMON as the bios on a pc and IOS like windows for cisco routers 

no, I asked him to remove flash Card so that we can test connection and typing in ROMMON mode.

oh ahahhhhahhahhah

In the following video step by step process has been shown how to Connect Cisco Router or Switch using PuTTY and Console Cable as well as how to Change Text Color, Font Size, Background color permanently on PuTTY.


First Download and install PuTTY (emulator terminal software) from

Step 1: Attach the DV9 Female end of Console cable with the DV9 Male end of the USB to DV9 Serial Converter and then connect the RJ54 connector end of the Console cable to the Cisco router or Switch.
