I forgot the password to my 1841 cisco series router so I used the CRTL+BREAK option, so that I can bypass the password but when I got to the Rommon prompt I typed in just 0x21 and just then I remembered the password so I rebooted the router, am not sure if I pressed ENTER on the keyboard before restarting the router.

The issue right now is that when I tried restarting the router it was just some funny shapes that were showing on y hyperterminal. I need help asap.

thanks
When you typed in 0x21 for the config register setting what you got was 0x0021, as the router will pad out the leading 8 bits in the hex number. Of course 0x0021 is different than 0x2100 !
So what did you get...

So bit 5 and bit 1 are set.

According to this link at Cisco »www.cisco.com/en/US/docs/routers···reg.html
... bits 5, 11 and 12 set the console bit rate
... bit 1 is in the boot field (see above)

So you've changed your console baud rate. This explains the weird characters. Now we have to find out what you changed it to. There is a table in that link above which indicates that when only bit 5 is set, but bits 11 and 12 are not, your console rate is 19200 bps. Voila! You have to change your terminal emulation program to 19200 bps and you'll be able to talk to your router again.
