	Asynchronous methods are comprised of two parts:		Asynchronous methods are comprised of two parts:
	* ~~The asynchronous~~ API call		* Asynchronous API call
	* ~~The asynchronous~~ handler		* Asynchronous handler

	When calling an asynchronous method, you must assign an asynchronous handler. The Phidget22 libraries will then initiate the command and immediately return. The asynchronous handler will be called once the relevant communications have been completed to provide the return code from the device.
