Yes.
Look at my IP Log Streaming Component using ICS, it includes a demo for

This is the simple test code to receive the data
procedure TForm1.WSocket1DataAvailable(Sender: TObject; ErrCode: Word);
begin
Inc(rec,1);
caption:= 'Received packets = '+inttostr(rec);
memo1.lines.add(WSocket2.ReceiveStr);
end;
