• In order to write applications using NDIS, one can use samples that accompany Microsoft's Windows Driver Kit (WDK). The 'PassThru' sample is a good starting point for intermediate drivers as it implements all the necessary details required in this driver type, but just passes the traffic through to the next driver in the chain.

Users utilize the USB GPS Port to connect to their GPS receivers and communicate with them. The GPS receiver permits real time navigation using tone's laptop for route positioning as well as graphical plotting. All the user has to do is load the GPS driver, plug in the GPS receiver to the USB port of the PC and install their own street mapping to be able to view their real-time position compared to the streets that are found around the travel area. Before the street mapping software is installed, the COM port must be configured so that it can accept the GPS receiver. It is only after this that the GPS receiver can be plugged into the laptop.

Users should note that they will need to change the mapping software's baud rate to 4800. If this is not done, the GPS data may not be accessed. Users of the USB GPS receiver are advised to plug the USB GPS in only after they have installed the USB driver. For the device to function effectively and efficiently, users are advised to always ensure that they are using the latest version of the device driver. Old versions have been known to create conflict and produce errors in the work in the work of the device.
