dm_tty_open Function

public function dm_tty_open(tty, path, baud_rate, byte_size, parity, stop_bits) result(rc)

Uses

    • unix
  • proc~~dm_tty_open~~UsesGraph proc~dm_tty_open dm_tty_open unix unix proc~dm_tty_open->unix

Opens TTY/PTS device in set access mode and applies serial port attributes. The arguments baud_rate, byte_size, parity, and stop_bits must be valid enumerators.

The function returns the following error codes:

  • E_EXIST if the TTY is already connected.
  • E_INVALID if the TTY parameters or flags are invalid.
  • E_IO if opening the TTY failed.
  • E_SYSTEM if setting the TTY attributes or flushing the buffers failed.

Arguments

integer, intent(in), optional :: baud_rate

Baud rate enumerator (TTY_B*).
integer, intent(in), optional :: byte_size

Byte size enumerator (TTY_BYTE_SIZE*).
integer, intent(in), optional :: parity

Parity enumerator (TTY_PARITY_*).
integer, intent(in), optional :: stop_bits

Stop bits enumerator (TTY_STOP_BITS*).

Return Value integer
