term

import "github.com/pkg/term"

Package term manages POSIX terminals. As POSIX terminals are connected to, or emulate, a UART, this package also provides control over the various UART and serial line parameters.

func CBreakMode

func CBreakMode(t *Term) error

CBreakMode places the terminal into cbreak mode.

func RawMode

func RawMode(t *Term) error

RawMode places the terminal into raw mode.

func Speed

func Speed(baud int) func(*Term) error

Speed sets the baud rate option for the terminal.

type Term

type Term struct {
    // contains filtered or unexported fields
}

Term represents an asynchronous communications port.

func Open

func Open(name string, options ...func(*Term) error) (*Term, error)

Open opens an asynchronous communications port.

func (*Term) Available

func (t *Term) Available() (int, error)

Available returns how many bytes are unused in the buffer.

func (*Term) Buffered

func (t *Term) Buffered() (int, error)

Buffered returns the number of bytes that have been written into the current buffer.

func (*Term) Close

func (t *Term) Close() error

Close closes the device and releases any associated resources.

func (*Term) DTR

func (t *Term) DTR() (bool, error)

DTR returns the state of the DTR (data terminal ready) signal.

func (*Term) Flush

func (t *Term) Flush() error

Flush flushes both data received but not read, and data written but not transmitted.

func (*Term) RTS

func (t *Term) RTS() (bool, error)

RTS returns the state of the RTS (data terminal ready) signal.

func (*Term) Read

func (t *Term) Read(b []byte) (int, error)

Read reads up to len(b) bytes from the terminal. It returns the number of bytes read and an error, if any. EOF is signaled by a zero count with err set to io.EOF.

func (*Term) Restore

func (t *Term) Restore() error

Restore restores the state of the terminal captured at the point that the terminal was originally opened.

func (*Term) SendBreak

func (t *Term) SendBreak() error

SendBreak sends a break signal.

func (*Term) SetCbreak

func (t *Term) SetCbreak() error

SetCbreak sets cbreak mode.

func (*Term) SetDTR

func (t *Term) SetDTR(v bool) error

SetDTR sets the DTR (data terminal ready) signal.

func (*Term) SetOption

func (t *Term) SetOption(options ...func(*Term) error) error

SetOption takes one or more option function and applies them in order to Term.

func (*Term) SetRTS

func (t *Term) SetRTS(v bool) error

SetRTS sets the RTS (data terminal ready) signal.

func (*Term) SetRaw

func (t *Term) SetRaw() error

SetRaw sets raw mode.

func (*Term) SetSpeed

func (t *Term) SetSpeed(baud int) error

SetSpeed sets the receive and transmit baud rates.

func (*Term) Write

func (t *Term) Write(b []byte) (int, error)

Write writes len(b) bytes to the terminal. It returns the number of bytes written and an error, if any. Write returns a non-nil error when n != len(b).
