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.

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