WebXON and XOFF appear as characters within the stream but should be processed as soon as possible. The characters received by the UART drivers are in intermediate buffers until TTY receives them. In the case where the TTY is not read from, the characters may get stuck into those intermediate buffers until user-space reads from the TTY.
