Cisco 1801 setup

Hey folks,

I have blown the dust of my Cisco 1801 and looke the books out to put a decent router on my network now I am running my own server however I have hit a few bumps but totally stick now. Any help?

DHCP is disabled and I can't remember the subnet.

Connected with the console cable but finding my admin password isn't accepted

Running the password recovery but unable to access ROMMON using special command > break

I should get this but the ATA monitor libray just loads and I get stuck on the password screen.

*** System received an abort due to Break Key ***

signal= 0x3, code= 0x500, context= 0x813ac158
PC = 0x802d0b60, Vector = 0x500, SP = 0x80006030
rommon 1 >

From what I gather (still green behind the ears) the ROMMON command has been disabled.

Any way to get into my Cisco or do I need to reload the IOS on the flash card?

Here is my event log/putty output

It doesn't show like rommon has been disabled. Check that not all USB adapters are able to send break correctly, so try another or an old PC with serial interface..

View solution in original post

An USB to Serial cable adapter would do also. Even on a newer computer. If Windows, I use Teraterm software. For linux, minicom.

Cheers folks, removing the USB to seriel cable and going direct from the com port on my server has solved it.Now I am to load a new IOS to the flash card?

My putty output in case it helps others
