This format is a protocol supports the MediaTek MT3339, a GPS 
chipset that shipped around 2011 that has internal logging capability.  
It is the 
core of at least two GPS modules, including the 
GlobalTop PA6H and the Fastrax IT530.  The GlobalTop PA6H module is in
turn the heart of the Adafruit "Ultimate" GPS breakout board, popular
in the Arduino "maker" world.
</p><p>
It is similar to the mtk and mtk-bin formats for earlier Mediatek parts.

      Speed in bits per second of serial port (autodetect=0).
    </p><p>The default is to autodetect the baudrate, but that can take a few seconds.  If you know the baudrate of the device it is faster to specify it explicitly.</p><p>Only valid when using a USB device as input.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_mtk_locus_o_download"></a><code class="option">download</code> option</h3></div></div></div><p>
      Download logged fixes.
    </p><p>This option processes a set of Locus fixes, by downloading it from an 
attached USB device or by reading records stored in a normal file.</p><p>You might want to disable this option if all you want to do is erase the memory 
or display the device status.  Downloading a large dataset can take several minutes
and while that is happening no other device commands can be executed.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_mtk_locus_o_erase"></a><code class="option">erase</code> option</h3></div></div></div><p>

    </p><p>This option displays the status of the device after the download is complete.
