You can list the available modems using the standard ObjectManager
interface and its GetManagedObjects() method:

org.freedesktop.DBus.ObjectManager.GetManagedObjects (out
DICT<OBJPATH,DICT<STRING,DICT<STRING,VARIANT>>>
objpath_interfaces_and_properties);

See https://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-objectmanager
