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 input and output buffers are flushed after connecting, unless argument flush is .false..

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

Type IntentOptional Attributes Name
type(tty_type), intent(inout) :: tty

TTY type.
character(len=*), intent(in), optional :: path

Device path.
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*).
logical, intent(in), optional :: flush

Do not flush buffers if .false..

Return Value integer
