terminalMode :: TerminalMode -> TerminalAttributes -> Bool withMode :: TerminalAttributes -> TerminalMode -> TerminalAttributes withoutMode :: TerminalAttributes -> TerminalMode -> TerminalAttributes bitsPerByte :: TerminalAttributes -> Int withBits :: TerminalAttributes -> Int -> TerminalAttributes controlChar :: TerminalAttributes -> ControlCharacter -> Maybe Char withCC :: TerminalAttributes -> (ControlCharacter, Char) -> TerminalAttributes withoutCC :: TerminalAttributes -> ControlCharacter -> TerminalAttributes inputTime :: TerminalAttributes -> Int withTime :: TerminalAttributes -> Int -> TerminalAttributes minInput :: TerminalAttributes -> Int withMinInput :: TerminalAttributes -> Int -> TerminalAttributes inputSpeed :: TerminalAttributes -> BaudRate withInputSpeed :: TerminalAttributes -> BaudRate -> TerminalAttributes outputSpeed :: TerminalAttributes -> BaudRate withOutputSpeed :: TerminalAttributes -> BaudRate -> TerminalAttributes getTerminalAttributes :: Fd -> IO TerminalAttributes

getTerminalAttributes fd calls tcgetattr to obtain the TerminalAttributes associated with Fd fd.

setTerminalAttributes :: Fd -> TerminalAttributes -> TerminalState -> IO ()

setTerminalAttributes fd attr ts calls tcsetattr to change the TerminalAttributes associated with Fd fd to attr, when the terminal is in the state indicated by ts.

sendBreak :: Fd -> Int -> IO ()

sendBreak fd duration calls tcsendbreak to transmit a continuous stream of zero-valued bits on Fd fd for the specified implementation-dependent duration.

drainOutput :: Fd -> IO ()

drainOutput fd calls tcdrain to block until all output written to Fd fd has been transmitted.

discardData :: Fd -> QueueSelector -> IO ()

discardData fd queues calls tcflush to discard pending input and/or output for Fd fd, as indicated by the QueueSelector queues.

controlFlow :: Fd -> FlowAction -> IO ()

controlFlow fd action calls tcflow to control the flow of data on Fd fd, as indicated by action.

getTerminalProcessGroupID :: Fd -> IO ProcessGroupID

getTerminalProcessGroupID fd calls tcgetpgrp to obtain the ProcessGroupID of the foreground process group associated with the terminal attached to Fd fd.

setTerminalProcessGroupID :: Fd -> ProcessGroupID -> IO ()

setTerminalProcessGroupID fd pgid calls tcsetpgrp to set the ProcessGroupID of the foreground process group associated with the terminal attached to Fd fd to pgid.
