// This structure is used for XOFF counter ioctl. The xoff ioctl
// is used to support those subsystems that feel the need to emulate
// the serial chip in software.
//
// It has the following semantics:
//
// This io request is placed into the normal device write
// queue. That is, it will be queued behind any writes
// already given to the driver.
//
// When this request becomes the current request, the character
// specified in the field XoffChar will be sent, subject to
// all other flow control already defined.
//
// Immediately upon sending the character the driver will
// perform the following actions.
//
// A timer will be initiated that will expire after the
// number of milliseconds in the Timeout field of the
// SERIAL_XOFF_COUNTER structure.
//
// The driver will initialize a counter to the value specified
// in the Counter field of the SERIAL_XOFF_RECORD. The driver
// will decrement this counter whenever a character is received.
//
// This request will then be held by the driver. It will
// actually complete under the following circumstances:
//
// 1) If there is another "write" request behind it in the queue.
// The "xoff" request will be completed with the informational status
// STATUS_SERIAL_MORE_WRITES. The Information field of the
// IOSTATUS block will be set to 0.
//
// Note: By write request we mean another SERIAL_XOFF_COUNTER
// request, or a simple write request. If the only subsequent
// request is a flush request, the driver WILL NOT automatically
// complete the SERIAL_XOFF_COUNTER request. NOTE: Transmit
// immediate requests DO NOT count as a normal write, and therefore
// would not cause a counter request to complete.
//
// 2) The timer expires. The driver will complete the request
// with the informational status STATUS_SERIAL_COUNTER_TIMEOUT.
// The Information field of the IOSTATUS of the request will be set to 0.
//
// 3) The driver maintained counter goes to zero. (By implication,
// at least "Counter" number of characters have been received.)
// The request will be completed with a successful status
// of STATUS_SUCCESS. The Information field of the
// IOSTATUS of the request will be set to 0.
//
// 4) This is really a degenerate case of "1" above. The request
// is started and no request follow it on the queue. However
// at some point, before "2" or "3" above occur, another "write"
// request is started. This will cause the completion actions
// stated in "1" to occur.
//
// NOTE: This request being issued WILL NOT cause the normal flow
// control code of the driver to be invoked.
//
// NOTE: This request has no interaction with the IOCTL_SERIAL_WAIT_ON_MASK
// request. An application CAN NOT wait via the above ^^^^^^ ioctl
// on the counter going to zero. The application must synchronize
// with the particular IOCTL_SERIAL_XOFF_COUNTER request.
//
// NOTE: The Timeout value equal to zero would cause the counter
// to NEVER timeout. The only way that such a request could
// be killed at that point would be issue another write, or
// to purge the WRITE queue.
