tcdrain
function waits until all output written to
the terminal referenced by fd has been transmitted to
the terminal.
The tcflow
function suspends transmission
of data to or the reception of data from the terminal referenced by
fd depending on the value of
action. The value of action must
be one of the following:

’ section of
termios(4)).The tcflush
function discards any data
written to the terminal referenced by fd which has not
been transmitted to the terminal, or any data received from the terminal but
not yet read, depending on the value of action. The
value of action must be one of the following:
The tcsendbreak
function transmits a
continuous stream of zero-valued bits for four-tenths of a second to the
terminal referenced by fd. The
len parameter is ignored in this implementation.
