Hi Pavel,

See these functions from gsm-sms.c:

API GSM_Error SendLongSMS(GSM_Data *data, GSM_Statemachine *state)
[...]
        count = (rawsms->UserDataLength + 127) / 128;
        printf("Will need %d sms-es\n", count);
        for (i=0; i<count; i++) {
                printf("Sending sms #%d\n", i);
                sms.UserData[0].Type = SMS_MultiData;
                sms.UserData[0].Length = 128;
                if (i+1 == count)
                        sms.UserData[0].Length = rawsms->UserDataLength % 128;
                memcpy(sms.UserData[0].u.Multi.Binary, rawsms->UserData + 
i*128, 128);
                sms.UserData[0].u.Multi.this = i+1;
                sms.UserData[0].u.Multi.total = count;
                sms.UserData[1].Type = SMS_NoData;
                data->SMS = &sms;
                error = SendSMS(data, state);
                if (error != GE_NONE) return error;
        }
        return GE_NONE;
[...]
API GSM_Error SendSMS(GSM_Data *data, GSM_Statemachine *state)
[...]
        if (data->RawSMS->Length > 171) {
                printf("SMS is too long? %d\n", data->RawSMS->Length);
                return SendLongSMS(data, state);
        }
[...]

Please explain:
 - where did you get "171", "127", "128" from?
 - how do you want to send concatenated messages (plain text
(default alphabet or unicode) messages with encoded length greater then
140 octets, shown by Nokia phones as "Linked #/#"?
