Thanks for all of the helpful suggestions here, and to rasoul for having
put in the time required to help figure this trick out!
For my part, I still haven't successfully executed MPX200_Backup.
The smartfon.inf driver, apparently for XP, does install under my
Starting the phone in modem mode does cause it to show up on the
list of active modems. It can be sent the standard query string, and
it does respond to that query.

I did find a note about disabling ActiveSync on the phone, but I am
unfamiliar with Windows for phones. I haven't had any luck in forcing
it to bring up a config screen: as soon as the unit finishes booting up,
it goes to an inescapable screen saying, "Insert SIM -- Emergency
Open to suggestions here, if anyone has any! Thanks.
