+ * Here is a brief description about how the fd driver works on windows.
+ *
+ * fd_init:
+ * For each in/out fd pair a threaded_reader and threaded_writer thread is
+ * created. Within the DriverData struct each of the threads have an AsyncIO
+ * sctruct associated with it. Within AsyncIO there are two important HANDLEs,
+ * ioAllowed and ov.hEvent. ioAllowed is used to signal the threaded_* threads
+ * should read/write some data, and ov.hEvent is driver_select'ed to be used to
+ * signal that the thread is done reading/writing.
+ *
+ * The reason for the driver being threaded like this is because once the FD is open
+ * on windows, it is not possible to set the it in overlapped mode. So we have to
+ * simulate this using threads.
+ *
+ * output:
+ * When an output occurs the data to be outputted is copied to AsyncIO.ov. Then
+ * the ioAllowed HANDLE is set, ov.hEvent is cleared and the port is marked as busy.
+ * The threaded_writer thread is lying in WaitForMultipleObjects on ioAllowed, and
+ * when signalled it writes all data in AsyncIO.ov and then sets ov.hEvent so that
+ * ready_output gets triggered and (potentially) sends the reply to the port and
+ * marks the port an non-busy.
+ *
+ * input:
+ * The threaded_reader is lying waiting in ReadFile on the in fd and when a new
+ * line is written it sets ov.hEvent that new data is available and then goes
+ * and waits for ioAllowed to be set. ready_input is run when ov.hEvent is set and
+ * delivers the data to the port. Then ioAllowed is signalled again and threaded_reader
+ * goes back to ReadFile.
+ *
+ * shutdown:
+ * In order to guarantee that all io is outputted before the driver is stopped,
+ * fd_stop uses flushEvent and flushReplyEvent to make sure that there is no data
+ * in ov which needs writing before returning from fd_stop.
