  This format is the serial download protocol for the MTK chips.   
  Mediatek's MT3301/3179 (MTKv1) and MT3318 (MTKv2) chips are used 
  in a large number of products sold under different names.  
</p><p>
  Many GPS products, especially of the data logger variety, expose 
  the Mediatek protocol to the user via USB.  Some modify Mediatek's 
  protocol in minor ways, but the core protocol is very commonly 
  seen in loggers.   
</p><p>
  The <a class="link" href="fmt_m241.html" title="Holux M-241 (MTK based) download (m241)">Holux M-241 and GPSport 245</a> 
  are examples of a device using an incompatible variation of the MTK 
  protocol.

The following products are known or are expected to work with this module.
As the products are typically very low cost, they tend to have a short 
product life cycle and are often imported to different areas under 
different names.  Keeping
track of the list is difficult.   Often the "same" GPS is sold in different
plastic or with different Windows software or different options such as 
compass or motion sensors or charging cables with different model numbers.
If you can confirm success with others, please share with us.

  The Mediatek chip offers a native serial port.   Data logger designers
  frequently pair this with commodity USB/Serial converter internally.  So
  these devices typically look like Prolific, FTDI, or Silab usb/serial 
  devices to the host OS.  You'll need drivers for that whatever chip 
  your product uses for your operating system.  For the "A+ GPS Recorder",
  the <a class="ulink" href="http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx" target="_top">Silicon Labs CP210x chip</a> is used.  On OS/X, you'll get
  awesome device names like /dev/cu.usbmodem1d13410 - fortunately, our GUI
  makes that multiple choice so you don't have to guess.

  Downloaded data will be stored in data.bin file in the current 
  directory together with the choosen output format.  This is a rather
  uncommon feature in GPSBabel's formats and is likely to change in future
  versions.

Most of the loggers cannot receive bluetooth commands; they can only send 
  data. Since GPSBabel needs to send commands to the GPS device it won't
  work. Download the data using the USB cable instead.
