Make sure you are not using a println() to write out your commands
since the "ln" part is platform dependent and typically not CRLF which
is probably not what telnet is looking for. Instead, use:
String CRLF = "\r\n";
String command = "telnet_command";
PrintWriter writer = new PrintWriter(socket.getOutputStream());
writer.write(command);
writer.write(CRLF);
writer.flush(); // flush the buffer!
