Problems with voice call.

With the Option iCON 225 USB modem the SMS error is sent in function
at_cmgf_query_cb() at line 795.

795                 return at_sms_not_supported(modem);

This is because the mode variable is always set to 0 at line 788
(while loop is executed only onces) and the supported stays at value FALSE:

788                 while (g_at_result_iter_next_number(&iter, &mode))
789                         if (mode == 1)
790                                 supported = TRUE;



I also tested oFono with the Nokia E51 phone which if I have understood
correctly supports of sending SMS messages at least on Windows
with PC Suite software. The result is a bit different.

With E51 the SMS error is returned from function at_cpms_query_cb()
on line 764.

764                 return at_sms_not_supported(modem);

This is because it does not go inside the while loop starting at line 741,
and the me_supported and sm_supported stays FALSE:

740
741                         while (g_at_result_iter_next_string(&iter, &store)) {
742                                 if (!strcmp(store, "ME"))
743                                         me_supported[mem] = TRUE;
744                                 else if (!strcmp(store, "SM"))
745                                         sm_supported[mem] = TRUE;
746                         }
747
