Special control characters are defined by the c cc array in the
termios structure. The subscript names and descriptions are as
follows:
VEOF EOF character
VEOL EOL character
VERASE ERASE character
VINTR INTR character
VKILL KILL character
VQUI T QUIT character
VSUSP SUSP character
VMIN MIN character
VT IME TIME character
If a modem disconnect is detected by the terminal interface for a
controlling terminal and if CLOCAL is not set in the c cflag
field for the terminal, a S I GHUP signal is sent to the controlling
process associated with the terminal. Unless other arrangements
were made (see signal(3», this causes the controlling process
to terminate.. Any subsequent read from the terminal device returns
an end-of-line indication until the device is closed. Thus,
processes that read a terminal file and test for end-of-file can terminate
appropriately after a disconnect Any subsequent
write(2) to the terminal device returns -1, with errno set
toE I 0, until the device is closed.
The last process to close a terminal device file shall cause any output
to be sent to the device and any input to be discarded. If
HUPCL is set in the control structure and the communications port
supports a disconnect function, the terminal device performs a
disconnect.
The following functions are provided for controlling the terminal
interface:
cfgetispeed(3P) Return the input baud rate.
cfgetospeed(3P) Return the output baud rate.
cfsetispeed(3P) Set the input baud rate.
cfsetospeed(3P) Set the output baud rate.
tcdrain(3P) Wait until all written data is transmitted.
tcflow(3P) Suspend or restart output or input.
tcfl ush(3P) Discard data not transmitted.
