I'm with trouble in +CDS return from channel. I'm using a modem with 64 channels and I need to get this value. This missing information in any lines above

I'm starting:

public PortaCOM(string porta)
    : base(porta, 115200, Parity.None, 8, StopBits.One)
{
    this.StatusPort = StatusPorta.Ready;
    this.DiscardNull = true;
    this.Handshake = Handshake.RequestToSend;
    //this.RtsEnable = true;
    //this.DtrEnable = true;
    //this.ReadTimeout = 12000;
    //this.ReadTimeout = 12000;
}

I get value using:

static void p_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
    var p = (PortaCOM)sender;
    try
    {

        int dataLength = p.BytesToRead;
        byte[] dados = new byte[dataLength];
        int nbrDataRead = p.Read(dados, 0, dataLength);
        if (nbrDataRead == 0)
            return;

        var retorno = Encoding.ASCII.GetString(dados);
        Console.WriteLine(retorno);
    }
    catch (Exception err) { Console.WriteLine(err.Message); }
}

Please, any help me!

  • Is this a problem only with `+CSD`? What results do you get from other commands that produce lots of responses like `at+cpbr=1,200` or `at+cmgl=4`. – hlovdal Mar 30 '13 at 22:49
  • Hello, I fixed error creating a loop: var b = new List(); while (p.BytesToRead > 0) b.Add((byte)p.ReadByte()); if (b.IsEmpty()) return; var retorno = Encoding.ASCII.GetString(b.ToArray()) – Ricardo Beck Mar 30 '13 at 23:27
  • If the problem is solved, please write the solution as an answer. – hlovdal Mar 31 '13 at 08:54

I changed inside p_DataReceived

    static void p_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        var p = (PortaCOM)sender;
        try
        {

           **var b = new List<byte>(); 
            while (p.BytesToRead > 0) 
                b.Add((byte)p.ReadByte()); 
            if (b.IsEmpty()) 
                return;**

            var retorno = Encoding.ASCII.GetString(b.ToArray());

            Console.WriteLine(retorno);
        }
        catch (Exception err) { Console.WriteLine(err.Message); }
    }
