[Bug 9986] serial/COM code misinterprets XON/XOFF direction

Some further explanation:

Many Linux sources mention:
    IXON        = Enable start/stop output control.
    IXOFF       = Enable start/stop input control.

I found some doc at http://www.ekf.de/c/ccom/drv_i960/ekf960mle.pdf that
explains:
    SERIAL_AUTO_TRANSMIT: Use the XON/XOFF protocol based flow control for
output.
    SERIAL_AUTO_RECEIVE : Use the XON/XOFF protocol based flow control for
input.
> From this we can conclude that:

IXON  <=> SERIAL_AUTO_TRANSMIT
    IXOFF <=> SERIAL_AUTO_RECEIVE

Unfortunately I do not have example code at hand.

I will attach a patch shortly.
