val sexp_of_t : t -> Sexplib0.Sexp.t
type setattr_when = UnixLabels.setattr_when =
  1. | TCSANOW
  2. | TCSADRAIN
  3. | TCSAFLUSH
val sexp_of_setattr_when : setattr_when -> Sexplib0.Sexp.t
val tcgetattr : File_descr.t -> t

Return the status of the terminal referred to by the given file descriptor.

val tcsetattr : t -> File_descr.t -> mode:setattr_when -> unit

Set the status of the terminal referred to by the given file descriptor. The second argument indicates when the status change takes place: immediately (TCSANOW), when all pending output has been transmitted (TCSADRAIN), or after flushing all input that has been received but not read (TCSAFLUSH). TCSADRAIN is recommended when changing the output parameters; TCSAFLUSH, when changing the input parameters.

val tcsendbreak : File_descr.t -> duration:int -> unit

Send a break condition on the given file descriptor. The second argument is the duration of the break, in 0.1s units; 0 means standard duration (0.25s).

val tcdrain : File_descr.t -> unit

Waits until all output written on the given file descriptor has been transmitted.

type flush_queue = UnixLabels.flush_queue =
  1. | TCIFLUSH
  2. | TCOFLUSH
  3. | TCIOFLUSH
val sexp_of_flush_queue : flush_queue -> Sexplib0.Sexp.t
val flush_queue_of_sexp : Sexplib0.Sexp.t -> flush_queue
val tcflush : File_descr.t -> mode:flush_queue -> unit

Discard data written on the given file descriptor but not yet transmitted, or data received but not yet read, depending on the second argument: TCIFLUSH flushes data received but not read, TCOFLUSH flushes data written but not transmitted, and TCIOFLUSH flushes both.

type flow_action = UnixLabels.flow_action =
  1. | TCOOFF
  2. | TCOON
  3. | TCIOFF
  4. | TCION
val sexp_of_flow_action : flow_action -> Sexplib0.Sexp.t
val flow_action_of_sexp : Sexplib0.Sexp.t -> flow_action
val tcflow : File_descr.t -> mode:flow_action -> unit

Suspend or restart reception or transmission of data on the given file descriptor, depending on the second argument: TCOOFF suspends output, TCOON restarts output, TCIOFF transmits a STOP character to suspend input, and TCION transmits a START character to restart input.

val setsid : unit -> int

Put the calling process in a new session and detach it from its controlling terminal.
