Can WinDriver share the Parallel/Serial port with Windows' drivers?

Windows does not allow sharing the port. Therefore, if you choose to use WinDriver to access the parallel/serial port, you may first need to disable Windows' parallel/serial port driver, then do your own I/O.

When handling the serial port's interrupt on Plug-and-Play systems (such as Windows 2000) you might also find that you need to uninstall Windows' serial port driver altogether and install an INF file that will notify the OS that WinDriver is handling the serial port.

Please note that in order to implement a standard serial port driver (which will replace Windows's serial port driver) you will need to use the KernelDriver tool-kit, which enables you to develop the driver entirely in the kernel (see Technical Document #2).
