This modem plugin is used on N900 running Maemo userspace already
controlling the phonet link and the N900 modem (csd and sscd).
The plugin uses the isigen driver for the N900 internal modem.
The n900maemo is compiled (while the normal n900 modem driver is
disabled) if ofono is configured with with --enable-n900modem option.
