I thought the modem already unpacks the ussd message to 8-bit gsm and
the dcs parameter is rather meaningless in that case. Perhaps the
atmodem ussd should re-pack the string in order to achieve the desired
symmetry on the API?

I agree with Pekka that maybe this should repack the 7-bit messages
into packed 7-bit, as this is what STK will be expecting in response
(I think). Also, why are we g_memdup'ing the content instead of using
directly?

The rule of thumb for patch submissions is to:
- Make sure all related chunks are together in one patch
- Chunks are only related to the particular change being described
- Unless impossible / extremely hard, the code should compile after each
individual patch.
In this case, please merge the chunks from patch #8 related to call
barring into this patch.

Since this patch uses structures from patch 7, it should come after

This patch modifies the driver API. All driver changes resulting from
this patch should follow after this patch. I'd move this patch to slot
#2 and patch #2 and #10 should come right after.

Should this return "not capable" only when !ussd_atom? If the other

3GPP 31.111 says that the terminal response to Send USSD should contain
a simple Text String. The DCS of the text string in STK is different
from DCS that is returned by USSD. Copying it directly from the USSD
DCS seems incorrect. Or is there something I'm missing?
On irc we figured that the best hint about what is expected to be
returned is in the tests in 31.124. +CUSD returns sms-like DCS, while
STK expects Cell Broadcast-like DCS and recommends using only the
values 00, 04, 08, so there needs to be a translation from one to the
other (perhaps in stk.c in the ussd callback). I think you'll also
need a length field in this struct as the data can contain 0s.

New subject: [PATCH 02/11] Changes done as per the changed driver API
Hi Pekka,
I thought the modem already unpacks the ussd message to 8-bit gsm and
the dcs parameter is rather meaningless in that case. Perhaps the
atmodem ussd should re-pack the string in order to achieve the
desired symmetry on the API?
Agree that the modem already unpacks the string received from the
network to the "character set" set by TE(UCS2 or UTF-8 or ...). Atom
driver will do the conversion to UTF-8 based on active character set
supported by modem, so it should have information of the active
character set. At present, we read and set the "character set" in the
phonebook atom driver. USSD atom driver could to do the same or the
reading/setting of character set can be done during the modem
initialisation (eg: atgen.c). I would prefer to have the reading and
setting of character set during the modem initialisation. I hope the
character set is not set by some other component apart from ofono :-)
