Sample program

 
 
<device_data>
	<device_id>local_printer</device_id>
	<data>
		<type>lock</type>
	</data>
</device_data>

Supplementary explanation

After executing <type>lock</type>, execute the <type>unlock</type> element before closing the application.

If you fail to do this, the device port cannot be locked for approximately 5 minutes until ePOSDevice
Service unlocks the port and ERROR_DEVICE_BUSY is passed to the <type>onreceive</type> element.
