Is it possible to support exec-out ?

How can I implement exec-out, just like this ?
```java
public InputStream executeOut(String command, String... args) throws IOException, JadbException {
    Transport transport = getTransport();
    StringBuilder shellLine = buildCmdLine(command, args);
    send(transport, "exec-out:" + shellLine.toString());
    return new BufferedInputStream(transport.getInputStream());
}
```
