Functions

func Cfgetispeed

func Cfgetispeed(attr *unix.Termios) uint32

Cfgetispeed returns the input baud rate stored in the termios structure.

func Cfgetospeed

func Cfgetospeed(attr *unix.Termios) uint32

Cfgetospeed returns the output baud rate stored in the termios structure.

func Cfmakecbreak

func Cfmakecbreak(attr *unix.Termios)

Cfmakecbreak modifies attr for cbreak mode.

func Cfmakeraw

func Cfmakeraw(attr *unix.Termios)

Cfmakeraw modifies attr for raw mode.

func Ptsname

func Ptsname(fd uintptr) (string, error)

func Pty

func Pty() (*os.File, *os.File, error)

Pty returns a UNIX 98 pseudoterminal device. Pty returns a pair of fds representing the master and slave pair.

func Tcdrain

func Tcdrain(fd uintptr) error

Tcdrain waits until all output written to the object referred to by fd has been transmitted.

func Tcflush

func Tcflush(fd, selector uintptr) error

Tcflush discards data written to the object referred to by fd but not transmitted, or data received but not read, depending on the value of selector.

func Tcgetattr

func Tcgetattr(fd uintptr, argp *unix.Termios) error

Tcgetattr gets the current serial port settings.

func Tcsendbreak

func Tcsendbreak(fd, duration uintptr) error

Tcsendbreak transmits 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.

func Tcsetattr

func Tcsetattr(fd, action uintptr, argp *unix.Termios) error

Tcsetattr sets the current serial port settings.

func Tiocinq

func Tiocinq(fd uintptr) (int, error)

Tiocinq returns the number of bytes in the input buffer.

func Tiocmbic

func Tiocmbic(fd uintptr, status int) error

Tiocmbic clears the indicated modem bits.

func Tiocmbis

func Tiocmbis(fd uintptr, status int) error

Tiocmbis sets the indicated modem bits.

func Tiocmget

func Tiocmget(fd uintptr) (int, error)

Tiocmget returns the state of the MODEM bits.

func Tiocmset

func Tiocmset(fd uintptr, status int) error

Tiocmset sets the state of the MODEM bits.

func Tiocoutq

func Tiocoutq(fd uintptr) (int, error)

Tiocoutq return the number of bytes in the output buffer.
