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.

Note that you cannot use WinDriver to implement a standard serial port driver that replaces Windows's serial port driver.
