Factory Reset procedure and/or default password for Nokia A021 accesspoint

Greetings:

This issue appears in usenet archives without any proper replies:
what is the factory reset procedure and/or default password
(on the serial port) for administering the Nokia A021 access point?

Nokia's meager online resources are silent on this issue,
referring the user to the operating manual for the unit, which
unfortunately is not online.

I have discovered a few Nokia employee e-mail addresses from the
responsible division which I will try later...

FWIW, my unit boots to a bridge mode and does not have an assigned
IP address, so the only communications channel to it is the serial
port. After the init. messages on the serial port, the unit
demands a password; I have tried many obvious ones unsuccessfully.
I have also tried power-cycle reset-button procedures that are
common to other devices; holding the reset button depressed while
applying power and waiting until the unit's LEDs all light and
then extinguish (about 10 seconds) causes a short binary output
to the serial port (which is then perhaps awaiting some sort of
upload).

All help much appreciated.

Michael
