| 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. | |
