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.

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