	The Holux m241 is a small datalogger using the MTK chipset, with 
	a couple small differences in the binary format. In its default 
	configuration, it can store ~100000 trackpoints with very limited
	 data; to configure extended logging you can use the BT747 open 
	source software 
         <a class="ulink" href="http://bt747.wiki.sourceforge.net" target="_top">bt747</a>
	 Waypoint storage is possible only if "recording reason" (RCR) is enabled in the settings.
</p><p>
	Holux GPSport 245 is a datalogger with display suitable for cycling, walking and running. 
        It can store ~200k trackpoints with limited data. The m241 and m241-bin format is 
        able to automatically detect GPSport 245 data and handle the differences from Holux 241 devices.
        Note: GP245 does not log any quality of the position.
</p><p>
	Use the m241 format to connect with the unit serially and m241-bin to read files saved by the device.
</p><p>
  This module is also reported to handle the Holux M1000c.
</p><p>
  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.

      Only erase device data, do not download anything.
    </p><p>This option will only erase the logger data. No data is downloaded.</p><p>This option is typically used as a second step after the data has been downloaded and verified.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_m241_o_log_enable"></a><code class="option">log_enable</code> option</h3></div></div></div><p>
      Enable logging after download.
    </p><p>This option will enable the logger after download.</p><p>By default the logger is re-enabled when download is finished if previously were enabled.
But if the download is aborted or failed the log functionality won't be enabled again.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="fmt_m241_o_csv"></a><code class="option">csv</code> option</h3></div></div></div><p>
      MTK compatible CSV output file.
    </p><p>
  Note that this option is a bit of an oddity in the GPSBabel arsenal.  This
  should probably be a "real" output type of its own instead of being bolted
  onto an input type.
