New Post: Commands are redisplayed before results are shown

When I run a command like "show vlan" I always get the following before the results are shown (and not exactly as I typed it). I'm using SignalR btw.

 ssh> show vlan
 show
 vlan
 s 

I just want to see the results of the command and not a jumbled display of the command. Here is a source snippet:

                shellStream = client.CreateShellStream(@"xterm", 80, 25, 640, 480, 1024);
                SshSteams.GetOrAdd("foo", shellStream);
                shellStream.DataReceived += StartAsyncRead;
                shellStream.Write(command + "\n");

    private void StartAsyncRead(object sender, EventArgs e)
    {
        ShellStream shellStream;
        try
        {
            if (!SshSteams.TryGetValue("foo", out shellStream))
            {
                Clients.All.receive("ERROR: ShellStream object not found");
                return;
            }

            shellStream.BeginRead(_data, 0, _data.Length, OnReadCompletion, new MyAsyncInfo(_data, shellStream));
        }
        catch (Exception)
        {
            throw;
        }
    }

    private void OnReadCompletion(IAsyncResult ar)
    {
        SshClient client;

        if (!SshClients.TryGetValue("foo", out client)) 
        {
            Clients.All.receive("ERROR: connection object not found");
            return;
        }

        try
        {
            var mai = (MyAsyncInfo)ar.AsyncState;
            int datalen = mai.Stream.EndRead(ar);
            string line = client.ConnectionInfo.Encoding.GetString(mai.ByteArray, 0, datalen);
            Clients.All.receive(line);
        }
        catch (Exception exception)
        {
            Clients.All.receive(exception);
        }
    }
