I found an old Cisco 1841 router and decided to boot it up to play with it a little. Everything seemed to be going ok but I guess something interrupted the boot. Last line is
%SYS-6-LOGGINGHOST_STARTSTOP: Logging to host 10.60.60.11 started - reconnectio
After this it just starts sending random characters over serial. What can I do to solve this?
Here's the entire log from the console:

    I would recommend to restart this router with 0x2142 and clear the configuration. You can find a lot of URL how do this in the Internet. For example this one sunsetlearning.com/password-recovery-for-cisco-routers – Konstantin Goncharenko Jul 16 '19 at 10:20

    This looks like a configuration where the console speed setting between ROMMON and IOS is different. – Ricky Jul 16 '19 at 16:10
  • Okay so tried to restart this router with 0x2142 but I ran into another issue...I can't type anything into the console over serial port. Could this be the issue with the serial port to USB adapter? – Ive Zenzerovic Jul 17 '19 at 20:40
  • Issue was in the cable...Got a new one and everything works fine :) – Ive Zenzerovic Jul 25 '19 at 12:55
