2 1. try {
2 2. String addr = "socket://host.com:79";
2 3. SocketConnection sc;
2 4. sc = (SocketConnection) Connector.open(addr);
2 5. sc.setSocketOption(SocketConnection.LINGER, 5);
2 6. InputStream is = sc.openInputStream();
2 7. OutputStream os = sc.openOutputStream();
2 8. os.write("\\r\\n".getBytes());
2 9. int ch = is.read();
3 0. // ...
3 5. } catch (IOException ioe) {
3 6. // ...
4 0. }
