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.

26 * QCDM-capable ports.  Devices that do not provide a CDC-ACM port should
27 * probably be driven by option.ko.
