![]() Those who passed their driving test before January 1997 generally have greater freedom with towing vehicles. You are able to tow a trailer over 750kg only if the vehicle you are driving is of a low enough weight that the total combined MAM of both the trailer and the vehicle is 3,500kg or less. If you passed after this date, you are permitted to drive a vehicle weighing up to 3,500kg, and can tow a trailer weighing up to 750kg MAM (maximum authorised mass). Legal restrictions vary depending on whether you passed your driving test before or after January 1997. If you are in possession of a full car licence, you can tow trailers of up to 750kg, or heavier trailers provided the total vehicle and trailer weight does not exceed 3500kg. Vendors of smart card reader devices must supply drivers that are designed to work with the system-supplied resource manager and smart card driver library.īoth native and vendor-supplied reader drivers must use the smart card driver library to perform many of their key operations, as explained in the section, Smart Card Driver Library.If you’re going to be towing a caravan or vehicle, it’s essential that you are aware of any limitations your driving license may have on the weights you can tow. For further information, see PCMCIA Smart Card Driver. The source code for this driver is available in the collection of WDK samples. Microsoft supplies one reader driver sample, pscr.sys, which is a driver for a PCMCIA smart card reader. If the reader driver is a WDM driver, the operating system will forward the request by means of an I/O request packet (IRP). Likewise, smart card-aware applications can send instructions to a smart card reader driver by means of DeviceIoControl, and the operating system will forward the indicated IOCTL to the reader driver. For information about how to use the DeviceIoControl system call, refer to the DeviceIoControl topic in the Microsoft Windows SDK. ![]() The resource manager communicates with the reader driver by means of I/O controls that are dispatched using the DeviceIoControl system call. The reader driver resides in kernel space, and the smart card resource manager resides in user space. ![]() ![]() In addition, the figure shows the following components of the smart card environment:Īpplications communicate with a smart card reader driver by means of the smart card resource manager. The following figure shows the standard environment for the smart card reader driver. ![]()
