Raw data I/O

[IODR100]

Hi
I have developed a connector with Qt that send instruction to equipement on my site.
This equipement located by it IP give an answer in three times
the instruction is 2 byte 0801
the response will be
- 4 bytes 08010d01.
- 32 bytes 00000..... (just zeros).
- 237 bytes 00000..0100000000000001010101010101000000000000000 000000. ( the first byte with 01 is the 16th one and the series of next 01
bytes are in position 101th.
but data that i recieved is:
- 4 bytes 08010d01.
- 32 bytes 0e1f134ffe..
- 237 bytes 000ffffffff0001deae8546796.......... (not expected data)

this is an extract of my code:

connect(socketts,SIGNAL(readyRead()),this,SLOT(recievedata()));
void M10::recievedata()
 
{
    QDataStream in(socketts);
        taillemessage=socketts->bytesAvailable();
         ui->taillebuffer->append (tr("La taille de la socket est : ")+QString::number(taillemessage));
         int row = ui->Notification->rowCount();
         QByteArray bab,buffer;
         bab.resize(taillemessage);
         buffer.resize(500);
         int sizebab = in.readRawData(bab.data(),bab.size());
 
{
             buffer=bab.data();
             buffer.resize(taillemessage);
 if(buffer.size()>2)
        {
             ui->textBrowser_2->append(buffer.toHex());
             QStringList fields1;
             ui->Notification->setRowCount(row+1);
             fields1 <<buffer.toHex()<<QString::number(buffer.size());
             for(int i=0;i<fields1.count();++i)
                 ui->Notification->setItem(row,i,new QTableWidgetItem(fields1[i]));
 
        taillemessage=0;
        }
         }
}

connect(socketts,SIGNAL(readyRead()),this,SLOT(recievedata()));
void M10::recievedata()

{
    QDataStream in(socketts);
        taillemessage=socketts->bytesAvailable();
         ui->taillebuffer->append (tr("La taille de la socket est : ")+QString::number(taillemessage));
         int row = ui->Notification->rowCount();
         QByteArray bab,buffer;
         bab.resize(taillemessage);
         buffer.resize(500);
         int sizebab = in.readRawData(bab.data(),bab.size());

{
             buffer=bab.data();
             buffer.resize(taillemessage);
 if(buffer.size()>2)
        {
             ui->textBrowser_2->append(buffer.toHex());
             QStringList fields1;
             ui->Notification->setRowCount(row+1);
             fields1 <<buffer.toHex()<<QString::number(buffer.size());
             for(int i=0;i<fields1.count();++i)
                 ui->Notification->setItem(row,i,new QTableWidgetItem(fields1[i]));

        taillemessage=0;
        }
         }
}

can you explain me why the data is not serialized correctly?
