  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.
