Here is my code to Read / Write with Delphi 7. Using the Tcp Event Read.

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ScktComp;

type
  TForm1 = class(TForm)
    ClientSocket1: TClientSocket;
    Button1: TButton;
    ListBox1: TListBox;
    Edit1: TEdit;
    Edit2: TEdit;
    procedure Button1Click(Sender: TObject);
    procedure ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket);
    procedure ClientSocket1Error(Sender: TObject; Socket: TCustomWinSocket;
      ErrorEvent: TErrorEvent; var ErrorCode: Integer);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
 UsePort: Integer;
 UseHost: String;

begin
UseHost := Edit1.Text;
UsePort := STRTOINT(Edit2.Text);
ClientSocket1.Port :=  UsePort;
ClientSocket1.Host :=  UseHost;
ClientSocket1.Active :=  true;
end;

procedure TForm1.ClientSocket1Read(Sender: TObject;
  Socket: TCustomWinSocket);
begin
ListBox1.Items.Add(ClientSocket1.Socket.ReceiveText);

end;

procedure TForm1.ClientSocket1Error(Sender: TObject;
  Socket: TCustomWinSocket; ErrorEvent: TErrorEvent;
  var ErrorCode: Integer);
begin
  ErrorCode:=0;
  ClientSocket1.Active := False;
end;

procedure TForm1.BitBtn1Click(Sender: TObject);
begin
  ClientSocket1.Socket.SendText(Edit1.Text);
end;

end.
