title: reading input interactively from "adb shell <command>"
body: <p>When I run <code>adb shell "read VAR?PROMPT"</code> on my computer, I get the <code>PROMPT</code>, but nothing I type seems to actually be sent to the remote shell (I have to press Ctrl+C to kill the <code>adb shell</code> process). It works when I use an interactive shell, so it looks like <code>adb shell &lt;command&gt;</code> maps only <code>stdout</code> and not <code>stdin</code>.</p>
  
  <p>Is there some workaround I can use to send input into a non-interactive command?</p>
