What can you do if you mistakenly type "confreg 0x2124" to reset a Cisco 881 instead of "0x2142"?

Thanks to the newer procedure for changing the password/username, I was attempting to reset the password.  I've done this several times before when taking over systems from other consultants.  This type the 42 was mistyped to 24 in confreg and now boot looks like Matrix code.  Figured I'd try her befor TAC.

most likely you have changed the port speed setting.
Try all settings till it makes sense.

looks to be 19200

0x2124 •NetBoot
•Ignores break
•Boots into ROM if initial boot fails
•19200 console speed
 
0x2142 •Ignores break
•Boots into ROM if initial boot fails
•9600 console baud rate
•Ignores the contents of Non-Volatile RAM (NVRAM) (ignores configuration)

Thanks guys!  That was quick.  I didnt even think about port speed or checking what the confreg codes were modifying exactly.
