11  * Devices listed here usually provide a CDC ACM port on which normal modem
12  * AT commands and PPP can be used.  But when that port is in-use by PPP it
13  * cannot be used simultaneously for status or signal strength.  Instead, the
14  * ports here can be queried for that information using the Qualcomm DM
15  * protocol.
