<h2>MicroPythonCommandsInterface</h2>

<p>
    Class implementing some file system commands for MicroPython.
</p>
<p>
    Commands are provided to perform operations on the file system of a
    connected MicroPython device. Supported commands are:
    <ul>
    <li>ls: directory listing</li>
    <li>lls: directory listing with meta data</li>
    <li>cd: change directory</li>
    <li>pwd: get the current directory</li>
    <li>put: copy a file to the connected device</li>
    <li>get: get a file from the connected device</li>
    <li>rm: remove a file from the connected device</li>
    <li>rmrf: remove a file/directory recursively (like 'rm -rf' in bash)
    <li>mkdir: create a new directory</li>
    <li>rmdir: remove an empty directory</li>
    </ul>
</p>
<p>
    There are additional commands related to time and version.
    <ul>
    <li>version: get version info about MicroPython</li>
    <li>getImplementation: get some implementation information</li>
    <li>syncTime: synchronize the time of the connected device</li>
    <li>showTime: show the current time of the connected device</li>
    </ul>
</p>
<h3>Signals</h3>
<dl>

<dt>dataReceived(data)</dt>
<dd>
emitted to send data received via the serial
        connection for further processing
</dd>
<dt>executeAsyncFinished()</dt>
<dd>
emitted to indicate the end of an
        asynchronously executed list of commands (e.g. a script)
</dd>
