Instance Variable _serialFactory a pyserial serial.Serial factory, used to create the instance stored in self._serial. Overrideable to enable easier testing.

Inherited from FileDescriptor (via BaseSerialPort):

Method doRead Called when data is available for reading.
Method doWrite Called when data can be written.
Method fileno File Descriptor number for select().
Method getHost Similar to getPeer, but returns an address describing this side of the connection.
Method getPeer Get the remote address of this connection.
Method loseConnection Close the connection at the next available opportunity.
Method loseWriteConnection Undocumented
Method pauseProducing Pause producing data.
Method readConnectionLost Indicates read connection was lost.
Method resumeProducing Resume producing data.
Method startReading Start waiting for read availability.
Method startWriting Start waiting for write availability.
Method stopConsuming Stop consuming data.
Method stopProducing Stop producing data.
Method stopReading Stop waiting for read availability.
Method stopWriting Stop waiting for write availability.
Method writeConnectionLost Indicates write connection was lost.
Method writeSequence Reliably write a sequence of data.
Method writeSomeData Write as much as possible of the given data, immediately.
Constant SEND_LIMIT Undocumented
Class Variable bufferSize Undocumented
Class Variable disconnecting Undocumented
Instance Variable dataBuffer Undocumented
Instance Variable disconnected Undocumented
Instance Variable offset Undocumented
Instance Variable producer Undocumented
Instance Variable producerPaused Undocumented
Method _closeWriteConnection Undocumented
Method _isSendBufferFull Determine whether the user-space send buffer for this transport is full or not.
Method _maybePauseProducer Possibly pause a producer, if there is one and the send buffer is full.
Method _postLoseConnection Called after a loseConnection(), when all data has been written.
Class Variable _writeDisconnected Undocumented
Instance Variable _tempDataBuffer Undocumented
Instance Variable _tempDataLen Undocumented
Instance Variable _writeDisconnecting Undocumented

Inherited from _ConsumerMixin (via BaseSerialPort, FileDescriptor):

Method registerProducer Register to receive data from a producer.
Method unregisterProducer Stop consuming data from a producer, without disconnecting.
Instance Variable streamingProducer bool or int

Inherited from _LogOwner (via BaseSerialPort, FileDescriptor, _ConsumerMixin):

Method logPrefix Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines.
Method _getLogPrefix Determine the log prefix to use for messages related to applicationObject, which may or may not be an interfaces.ILoggingContext provider.
def __init__(self, protocol, deviceNameOrPortNumber, reactor, baudrate=9600, bytesize=EIGHTBITS, parity=PARITY_NONE, stopbits=STOPBITS_ONE, xonxoff=0, rtscts=0): (source)
reactorAn IReactorFDSet provider which this descriptor will use to get readable and writeable event notifications. If no value is given, the global reactor will be used.
def connectionLost(self, reason): (source)

Called when the serial port disconnects.

Will call connectionLost on the protocol that is handling the serial data.

def serialReadEvent(self): (source)


def serialWriteEvent(self): (source)


def write(self, data): (source)

Reliably write some data.

The data is buffered until the underlying file descriptor is ready for writing. If there is more than self.bufferSize data in the buffer and this descriptor has a registered streaming producer, its pauseProducing() method will be called.


closedNotifies: int = (source)


outQueue: list = (source)


protocol = (source)


read_buf = (source)


writeInProgress: int = (source)


def _clearCommError(self): (source)


def _finishPortSetup(self): (source)

Finish setting up the serial port.

This is a separate method to facilitate testing.
