How to Reset Password on 3Com Switch 4005?

Last Modified: 2012-05-08
I have a 3Com Switch 4005 that I cannot get into to configure.  The password went away with the previous net admin (and yes, I already tried the default username with no password).  The user guide says to use the "system control initialize" command, but I don't see how to get CLI access through the console (serial) port without knowing the password.

I also found a recommended method to force a TFTP firmware update to reset the password, but that requires a reset button, which this switch apparently does not have.
