-- Disables the DTR line when the device is opened

-- the RTS line when the buffer is more than three-quarters full.
-- When in use the RTS line can not be directly controlled.

-- Specifies that the RTS line will be high if bytes are available
-- for transmission. After all buffered bytes have been sent, the
-- RTS line will be low. Not available on Windows Me/98/95
