Thanks for the responses. I'm using Java, and this is the code-snippet: String command1=new String(""); String command=new String(""); try { Socket sock=new Socket(new String("192.168.1.5"), 6543); DataInputStream dis=new DataInputStream(sock.getInputStream()); PrintStream ps=new PrintStream(sock.getOutputStream()); command1="MYTH_PROTO_VERSION 19"; command=command1.length()+1 + " " + command1; System.out.println(command); ps.print(command); System.out.println(dis.readLine()); sock.close(); } catch (Exception x) { x.printStackTrace(); } System.exit(0); which results in 22 MYTH_PROTO_VERSION 19 13 REJECT[]:[]19 I'm fairly sure the problem lies with the line: command=command1.length()+1 + " " + command1; originally this was just: command=command1.length() + command1; but this (and a dozen other variations!) resulted in absolutely no response from the backend. The line, as it stands, is the only thing to get any response at all! What I want to be able to do (eventually) is call mythbackend to reschedule the recordings, as I've written a java utility that searches for tv programs based on keywords and allows the user to select shows for recording. The code to insert the data into mythconverg.record is all working, I just need to be able to do a reschedule. As I understand it, I should do something like: xx MYTH_PROTO_VERSION 19 ACCEPTED xx ANN Playback Myputer 0 ACCEPTED xx RESCHEDULE_RECORDINGS -1 Thanks again Neil
