Hi Denis,

we figured out the problem:

At the end of a PPP connection, garbage was passed in to the AT command =

parser on the modem chat.
This garbage contained a doublequote, which switched the AT syntax =

parser into string mode.
However, because no second doublequote arrived, it stayed in this mode, =

and kept returning UNSURE result.

I think this is an major issue that should be fixed in oFono.
The syntax parser has to be extended to handle such cases.

Regards,
Marko
