Reporter Note

Report has been created using Wammu 0.32.1.

The Sierra Wireless MC8781 is a mini PCI-express mobile broadband card for installation inside a laptop or netbook.

Making calls is not expected to be possible, since the device has no audio interface (that I am aware of). It is possible to view the list of previous outgoing calls, which I presume contains a list of data connections made.

The device is supported by the 'sierra' Linux kernel module, which provides /dev/ttyUSB2, through which Gammu can connect, provided that a mobile broadband session is not in progress. It is necessary to wait a while before using Gammu/Wammu after ending a mobile broadband connection.

Outgoing SMS messages do not acquire a date/time. I have assumed that this a shortcoming of the device itself.
