Hi Denis, > The original USSD API actually did look like this. It used binary data > + dcs field. However, we quickly found that all modems are screwed up > in this area. The specification added binary PDU mode to SMS and CBS, but never bothered with USSD. So all modems get this part wrong.

If the Send USSD proactive command is > not handled by the modem, then oFono will try to do its best. However, we make no guarantees ;) I think its better to send the dcs and the binary data to the atom driver. If the modem doesn't support other than GSM 7-bit alphabet, then the conversion can be done in the atom driver. This way it will be general to any modem. Let me know your views on this.
