[PATCH 1/3] Bluetooth DUN modem prototype

[PATCH 1/3] Bluetooth DUN modem prototype

[Gustavo F. Padovan]

[-- Attachment #1: Type: text/plain, Size: 10487 bytes --]

Add a still dummy DUN code, now it can only creates and removes modems.
The DUN plugin follows the HFP one a lot, the is basics a copy of some
HFP plugin's parts.

[PATCH 2/3] Add dun_enable() function

[Gustavo F. Padovan]

[-- Attachment #1: Type: text/plain, Size: 3145 bytes --]

dun_enable() is called by setting the Powered property to true.
It creates a rfcomm link throught the BlueZ Serial API.

You might want to power on modem before jumping to this label. If there's any error
from dbus, you power off but then power on the modem again. It's wrong.

Shall we define a macro like DBUS_TIMEOUT instead of hard code 15 seconds?
What do you think?

One more comment here, I'd suggest to use g_strdup(dev). Because the device
String is from dbus reply and later we will unref the reply. What do you think?

Here the function exceeds 80 characters. So we should add a return after gpointer value.

Btw, I meet following message when applying your patch. I'd suggest you to remove extra line
at EOF.

Applying: ...
