How to get 1841 into default bit rate 9600 ?

I was in rommon mode trying to fix a problem with ios of a 1841 router. When changing bit rate using the command (confreg),

 

rommon 1 >confreg
Configuration Summary 
enabled are: 
break/abort has effect 
console baud: 9600 
boot: the ROM Monitor

do you wish to change the configuration? y/n [n]: y
enable "diagnostic mode"? y/n [n]:
enable "use net in IP bcast address"? y/n [n]:
enable "load rom after netboot fails"? y/n [n]:
enable "use all zero broadcast"? y/n [n]:
disable "break/abort has effect"? y/n [n]:
enable "ignore system config info"? y/n [n]:
change console baud rate? y/n [n]: y
enter rate: 0 = 9600, 1 = 4800, 2 = 1200, 3 = 2400
4 = 19200, 5 = 38400, 6 = 57600, 7 = 115200 [0]: 

 

I do not know what did I choose exactly, I restarted the router then I got lost!!!!! I tried changing bit rate of hyperterminal several times, each time I used a different bit rate but it is not working..... each time I get the same blank (white) screen of hyperterminal.

Please help me to get the right bit rate or whatever to get to the rommon mode again.

From ROMmon enter the command "unset BAUD". Enter the exact command (including the upper case).

Thank you, I think it worked. All what I did is I just copied the command you gave to the hyperterminal screen then I saw lots of " i($%^*&*$^))#$^&*#$&%@#^!#*!)#*%&%$*#(@(@))_ " going up and down I knew that it changed the bit rate to 2400. Now it is fine thank you.
