Inserting SOH and EOT into stream

Question

Hi all,
I have a problem , I need to my socket client to bind and establish a socket connection to a remote server. Once the port has bounded the server expects a start of header, some text and end of text.
The networking code work fine but I cant insert the SOH & EOT into the stream, every time I do it concatanates the string and converts my unicode values to string represenations. Heres the string that I am trying to send...
byte SOH = 0x01;
byte EOT = 0x04;
String message = SOH + "803001HWDEMP447........" + EOT;
outputstream.write(message.getBytes());The server accepts the connection and receives '01803001.......04", can anyone help in encoding this string?

Answer 1

It's the conversion to and from a String. Don't convert the SOH and EOT into a String, just write them separately as bytes.
byte SOH = 0x01;
byte EOT = 0x04;
OutputStream outputstream = new BufferedOutputStream(socket.getOutputStream());
String message = "803001HWDEMP447........";
outputstream.write(SOH);
outputstream.write(message.getBytes());
outputstream.write(EOT);
outputstream.flush();
