Sending Chararray of hexadecimal

Question

Hi everyone.
im trying to send a chararray of hexadecimal in a socket, but when i catch it on the server it's not the same chararray...
this is the array i am sending from the client:
  char[] _envio = {0x00,0x4C,0x60,0x00,0x05,0x80,0xE3,0x08,0x00,0x20,0x20,0x61,0x01,0x80,0xC0,0x00,0x02,
                        0x95,0x00,0x00,0x01,0x05,0x82,0x12,0x34,0x01,0x23,0x00,0x01};and this is what i am getting on the server:
0 4C 60 05 3F E3 8 0 20 20 61 1 3F C0 02 3F 0 0 15 3F12 34 1 23 01
note that the problem is when the hexadecimal is 0x80, 0x95 and 0x82 it is always change by 3F...
can someone tell me why this is happening?
this is how i am sending the chararray
char[] _envio = {0x00,0x4C,0x60,0x00,0x05,0x80,0xE3,0x08,0x00,0x20,0x20,0x61,0x01,0x80,0xC0,0x00,0x02,
                        0x95,0x00,0x00,0x01,0x05,0x82,0x12,0x34,0x01,0x23,0x00,0x01};
        try
            _serversocket = new Socket(_ipserver, _portserver);
            _out = new PrintStream(_serversocket.getOutputStream());
            _in = new BufferedReader(new InputStreamReader(
                _serversocket.getInputStream()));
              _out.println(_envio);
        catch (UnknownHostException ex)
            ex.printStackTrace();
        }and this is how i am chatching it in the server
try
                _in = new BufferedReader(new InputStreamReader(
                        _clientsocket.getInputStream()));
                _out = new PrintStream(_clientsocket.getOutputStream());
                _in.read(_msj);
                System.out.print("Mensaje del cliente: ");
                for(int i = 0; i < _msj.length; i++)
                   System.out.print(Integer.toHexString((int)_msj).toUpperCase());
System.out.println();
catch (IOException ex)
ex.printStackTrace();

Instead of PrintStream and BufferedReader (with InputStreamReader) you should use [url http://java.sun.com/j2se/1.5.0/docs/api/java/io/DataOutputStream.html#writeChar(int)]DataOutputStream.writeChar() and [url http://java.sun.com/j2se/1.5.0/docs/api/java/io/DataInputStream.html#readChar()]DataInputStream.readChar() because there is no special conversion involved.// client:
_out = new DataOutputStream(_serversocket.getOutputStream());
for (int i = 0; i < _envio.length; i++)
    _out.writeChar(_envio);
// server:
in = new DataInputStream(clientsocket.getInputStream());
for (int i = 0; i < _msj.length; i++)
_msj[i] = _in.readChar();Regards
