# termios - pydoc - phpman Help on module termios: ## NAME termios ## MODULE REFERENCE The following documentation is automatically generated from the Python source files. It may be incomplete, incorrect or include features that are considered implementation detail and may vary between Python implementations. When in doubt, consult the module reference at the location listed above. ## DESCRIPTION This module provides an interface to the Posix calls for tty I/O control. For a complete description of these calls, see the Posix or Unix manual pages. It is only available for those Unix versions that support Posix termios style tty I/O control. All functions in this module take a file descriptor fd as their first argument. This can be an integer file descriptor, such as returned by sys.stdin.fileno(), or a file object, such as sys.stdin itself. ## CLASSES builtins.Exception(builtins.BaseException) error ### class error | Method resolution order: | error | builtins.Exception | builtins.BaseException | builtins.object | | Data descriptors defined here: | | __weakref__ | list of weak references to the object (if defined) | | ---------------------------------------------------------------------- | Methods inherited from builtins.Exception: | | __init__(self, /, *args, **kwargs) | Initialize self.

The action argument can be termios.TCOOFF to suspend output, termios.TCOON to restart output, termios.TCIOFF to suspend input, or termios.TCION to restart input. ### tcflush Discard queued data on file descriptor fd. The queue selector specifies which queue: termios.TCIFLUSH for the input queue, termios.TCOFLUSH for the output queue, or termios.TCIOFLUSH for both queues. ### tcgetattr Get the tty attributes for file descriptor fd. Returns a list [iflag, oflag, cflag, lflag, ispeed, ospeed, cc] where cc is a list of the tty special characters (each a string of length 1, except the items with indices VMIN and VTIME, which are integers when these fields are defined). The interpretation of the flags and the speeds as well as the indexing in the cc array must be done using the symbolic constants defined in this module. ### tcsendbreak Send a break on file descriptor fd. A zero duration sends a break for 0.25-0.5 seconds; a nonzero duration has a system dependent meaning. ### tcsetattr Set the tty attributes for file descriptor fd. The attributes to be set are taken from the attributes argument, which is a list like the one returned by tcgetattr(). The when argument determines when the attributes are changed: termios.TCSANOW to change immediately, termios.TCSADRAIN to change after transmitting all queued output, or termios.TCSAFLUSH to change after transmitting all queued output and discarding all queued input. ## DATA B0 = 0 B1000000 = 4104 B110 = 3 B115200 = 4098 B1152000 = 4105 B1200 = 9 B134 = 4 B150 = 5 B1500000 = 4106 B1800 = 10 B19200 = 14 B200 = 6 B2000000 = 4107 B230400 = 4099 B2400 = 11 B2500000 = 4108 B300 = 7 B3000000 = 4109 B3500000 = 4110 B38400 = 15 B4000000 = 4111 B460800 = 4100 B4800 = 12 B50 = 1 B500000 = 4101 B57600 = 4097 B576000 = 4102 B600 = 8 B75 = 2 B921600 = 4103 B9600 = 13 BRKINT = 2 BS0 = 0 BS1 = 8192 BSDLY = 8192 CBAUD = 4111 CBAUDEX = 4096 CDSUSP = 25 CEOF = 4 CEOL = 0 CEOT = 4 CERASE = 127 CFLUSH = 15 CIBAUD = 269418496 CINTR = 3 CKILL = 21 CLNEXT = 22 CLOCAL = 2048 CQUIT = 28 CR0 = 0 CR1 = 512 CR2 = 1024 CR3 = 1536 CRDLY = 1536 CREAD = 128 CRPRNT = 18 CRTSCTS = 2147483648 CS5 = 0 CS6 = 16 CS7 = 32 CS8 = 48 CSIZE = 48 CSTART = 17 CSTOP = 19 CSTOPB = 64 CSUSP = 26 CWERASE = 23 ECHO = 8 ECHOCTL = 512 ECHOE = 16 ECHOK = 32 ECHOKE = 2048 ECHONL = 64 ECHOPRT = 1024 EXTA = 14 EXTB = 15 FF0 = 0 FF1 = 32768 FFDLY = 32768 FIOASYNC = 21586 FIOCLEX = 21585 FIONBIO = 21537 FIONCLEX = 21584 FIONREAD = 21531 FLUSHO = 4096 HUPCL = 1024 ICANON = 2 ICRNL = 256 IEXTEN = 32768 IGNBRK = 1 IGNCR = 128 IGNPAR = 4 IMAXBEL = 8192 INLCR = 64 INPCK = 16 IOCSIZE_MASK = 1073676288 IOCSIZE_SHIFT = 16 ISIG = 1 ISTRIP = 32 IUCLC = 512 IXANY = 2048 IXOFF = 4096 IXON = 1024 NCC = 8 NCCS = 32 NL0 = 0 NL1 = 256 NLDLY = 256 NOFLSH = 128 N_MOUSE = 2 N_PPP = 3 N_SLIP = 1 N_STRIP = 4 N_TTY = 0 OCRNL = 8 OFDEL = 128 OFILL = 64 OLCUC = 2 ONLCR = 4 ONLRET = 32 ONOCR = 16 OPOST = 1 PARENB = 256 PARMRK = 8 PARODD = 512 PENDIN = 16384 TAB0 = 0 TAB1 = 2048 TAB2 = 4096 TAB3 = 6144 TABDLY = 6144 TCFLSH = 21515 TCGETA = 21509 TCGETS = 21505 TCIFLUSH = 0 TCIOFF = 2 TCIOFLUSH = 2 TCION = 3 TCOFLUSH = 1 TCOOFF = 0 TCOON = 1 TCSADRAIN = 1 TCSAFLUSH = 2 TCSANOW = 0 TCSBRK = 21513 TCSBRKP = 21541 TCSETA = 21510 TCSETAF = 21512 TCSETAW = 21511 TCSETS = 21506 TCSETSF = 21508 TCSETSW = 21507 TCXONC = 21514 TIOCCONS = 21533 TIOCEXCL = 21516 TIOCGETD = 21540 TIOCGICOUNT = 21597 TIOCGLCKTRMIOS = 21590 TIOCGPGRP = 21519 TIOCGSERIAL = 21534 TIOCGSOFTCAR = 21529 TIOCGWINSZ = 21523 TIOCINQ = 21531 TIOCLINUX = 21532 TIOCMBIC = 21527 TIOCMBIS = 21526 TIOCMGET = 21525 TIOCMIWAIT = 21596 TIOCMSET = 21528 TIOCM_CAR = 64 TIOCM_CD = 64 TIOCM_CTS = 32 TIOCM_DSR = 256 TIOCM_DTR = 2 TIOCM_LE = 1 TIOCM_RI = 128 TIOCM_RNG = 128 TIOCM_RTS = 4 TIOCM_SR = 16 TIOCM_ST = 8 TIOCNOTTY = 21538 TIOCNXCL = 21517 TIOCOUTQ = 21521 TIOCPKT = 21536 TIOCPKT_DATA = 0 TIOCPKT_DOSTOP = 32 TIOCPKT_FLUSHREAD = 1 TIOCPKT_FLUSHWRITE = 2 TIOCPKT_NOSTOP = 16 TIOCPKT_START = 8 TIOCPKT_STOP = 4 TIOCSCTTY = 21518 TIOCSERCONFIG = 21587 TIOCSERGETLSR = 21593 TIOCSERGETMULTI = 21594 TIOCSERGSTRUCT = 21592 TIOCSERGWILD = 21588 TIOCSERSETMULTI = 21595 TIOCSERSWILD = 21589 TIOCSER_TEMT = 1 TIOCSETD = 21539 TIOCSLCKTRMIOS = 21591 TIOCSPGRP = 21520 TIOCSSERIAL = 21535 TIOCSSOFTCAR = 21530 TIOCSTI = 21522 TIOCSWINSZ = 21524 TOSTOP = 256 VDISCARD = 13 VEOF = 4 VEOL = 11 VEOL2 = 16 VERASE = 2 VINTR = 0 VKILL = 3 VLNEXT = 15 VMIN = 6 VQUIT = 1 VREPRINT = 12 VSTART = 8 VSTOP = 9 VSUSP = 10 VSWTC = 7 VSWTCH = 7 VT0 = 0 VT1 = 16384 VTDLY = 16384 VTIME = 5 VWERASE = 14 XCASE = 4 XTABS = 6144 ## FILE /usr/lib/python3.10/lib-dynload/termios.cpython-310-x86_64-linux-gnu.so
