Additional custom properties can easily be integrated into any application. This feature eliminates the need for programmers to determine how to extract a particular field from a string of data. More importantly, the parsing can be modified via templates without requiring any changes to the application program. Devices communicate via data streams, not packets. Responses from devices are inherently asynchronous.
Most devices maintain a communication protocol of some kind.
Devices may attach to the host in different ways. The MagTek Device Drivers resolve these issues by offering a simple device control language that supports most of the functionality of the MagTek devices. The control language is implemented by a driver, which completes the solution for the application developer. Gives easy access to the device. Hides the communication protocol.
