Returns the input baud rate stored in the termios structure.

source

# TERMIOS.cfgetospeed — Method.

cfgetospeed(term::termios) -> Int

Returns the output baud rate stored in the termios structure.

source

# TERMIOS.cfmakeraw — Method.

cfmakeraw(term::termios)

Set the terminal to something like the "raw" mode of the old Version 7 terminal driver: input is available character by character, echoing is disabled, and all special processing of terminal input and output characters is disabled. The terminal attributes are set as follows:

term.c_iflag &= ~(IGNBRK | BRKINT | PARMRK | ISTRIP
             | INLCR | IGNCR | ICRNL | IXON);
term.c_oflag &= ~OPOST;
term.c_lflag &= ~(ECHO | ECHONL | ICANON | ISIG | IEXTEN);
term.c_cflag &= ~(CSIZE | PARENB);
term.c_cflag |= CS8;

source

# TERMIOS.cfsetispeed — Method.

cfsetispeed(term::termios, speed::Integer)

sets the input baud rate stored in the termios structure to speed, which must be one of these constants:

TERMIOS.B0
TERMIOS.B50
TERMIOS.B75
TERMIOS.B110
TERMIOS.B134
TERMIOS.B150
TERMIOS.B200
TERMIOS.B300
TERMIOS.B600
TERMIOS.B1200
TERMIOS.B1800
TERMIOS.B2400
TERMIOS.B4800
TERMIOS.B9600
TERMIOS.B19200
TERMIOS.B38400
TERMIOS.B57600
TERMIOS.B115200
TERMIOS.B230400

The zero baud rate, B0, is used to terminate the connection. If B0 is specified, the modem control lines shall no longer be asserted. Normally, this will disconnect the line. CBAUDEX is a mask for the speeds beyond those defined in POSIX.1 (57600 and above). Thus, B57600 & CBAUDEX is nonzero.

source

# TERMIOS.cfsetospeed — Method.

cfsetospeed(term::termios, speed::Integer)

sets the output baud rate stored in the termios structure to speed, which must be one of these constants:

TERMIOS.B0
TERMIOS.B50
TERMIOS.B75
TERMIOS.B110
TERMIOS.B134
TERMIOS.B150
TERMIOS.B200
TERMIOS.B300
TERMIOS.B600
TERMIOS.B1200
TERMIOS.B1800
TERMIOS.B2400
TERMIOS.B4800
TERMIOS.B9600
TERMIOS.B19200
TERMIOS.B38400
TERMIOS.B57600
TERMIOS.B115200
TERMIOS.B230400

The zero baud rate, B0, is used to terminate the connection. If B0 is specified, the modem control lines shall no longer be asserted. Normally, this will disconnect the line. CBAUDEX is a mask for the speeds beyond those defined in POSIX.1 (57600 and above). Thus, B57600 & CBAUDEX is nonzero.

source

# TERMIOS.cfsetspeed — Method.

cfsetspeed(term::termios, speed::Int)

is a 4.4BSD extension. It takes the same arguments as cfsetispeed(), and sets both input and output speed.

source

# TERMIOS.tcdrain — Method.

tcdrain(s::Base.LibuvStream)

Wait until all output written to file descriptor fd has been transmitted.

source

# TERMIOS.tcflow — Method.

tcflow(s::Base.LibuvStream, action::Integer)

Suspend transmission or reception of data on the object referred to by fd, depending on the value of action:

TERMIOS.TCOOFF to suspend output,
TERMIOS.TCOON to restart output
TERMIOS.TCIOFF to suspend input,
TERMIOS.TCION to restart input.

source

# TERMIOS.tcflush — Method.

tcflush(s::Base.LibuvStream, queue::Integer)

Discard data written to the object referred to by fd but not transmitted, or data received but not read, depending on the value of queue_selector:

TERMIOS.TCIFLUSH flushes data received but not read.
TERMIOS.TCOFLUSH flushes data written but not transmitted.
TERMIOS.TCIOFLUSH flushes both data received but not read, and data written but not transmitted.

source

# TERMIOS.tcgetattr — Method.

tcgetattr(fd::RawFD, term::termios)
tcgetattr(s::Base.LibuvStream, term::termios)
tcgetattr(f::Int, term::termios)

Get the tty attributes for file descriptor fd

source

# TERMIOS.tcsendbreak — Method.

tcsendbreak(s::Base.LibuvStream, duration::Integer)

Transmit a continuous stream of zero-valued bits for a specific duration, if the terminal is using asynchronous serial data transmission. If duration is zero, it transmits zero-valued bits for at least 0.25 seconds, and not more that 0.5 seconds. If duration is not zero, it sends zero-valued bits for some implementation-defined length of time.

If the terminal is not using asynchronous serial data transmission, tcsendbreak() returns without taking any action.

source

# TERMIOS.tcsetattr — Method.

tcsetattr(s::Base.LibuvStream, when::Integer, term::termios)

Set the tty attributes for file descriptor fd. The when argument determines when the attributes are changed:

TERMIOS.TCSANOW to change immediately
TERMIOS.TCSADRAIN to change after transmitting all queued output
TERMIOS.TCSAFLUSH to change after transmitting all queued output and discarding all queued input.
