Hello,
I have a PCI interface card, which has several serial ports. My goal is to expose those serial ports as individual Virtual COM Ports in Windows. There is already an existing function driver for the device. Therefore I would like to add a corresponding filter driver on top of the device driver. However, I am pretty new to Windows Driver Development and do not really know, where to start from. Is something like this possible with the filter-driver approach, as the device driver and filter driver will not have the same ClassGuid? Can somebody please guide me in the right direction, on which driver model to use?
Thanks in advance
