t.i.s.SerialPort(BaseSerialPort, abstract.FileDescriptor) : class documentation

Part of twisted.internet.serialport View Source View In Hierarchy

A serial device, acting as a transport, that uses a win32 event.
Method __init__ Undocumented
Method serialReadEvent Undocumented
Method write Reliably write some data.
Method serialWriteEvent Undocumented
Method connectionLost Called when the serial port disconnects.
Method _finishPortSetup Finish setting up the serial port.

Inherited from BaseSerialPort:

Method setBaudRate Undocumented
Method inWaiting Undocumented
Method flushInput Undocumented
Method flushOutput Undocumented
Method sendBreak Undocumented
Method getDSR Undocumented
Method getCD Undocumented
Method getRI Undocumented
Method getCTS Undocumented
Method setDTR Undocumented
Method setRTS Undocumented
Instance Variable _serialFactory a pyserial serial.Serial factory, used to create the instance stored in self._serial. Overrideable to enable easier testing.
Instance Variable _serial a pyserial serial.Serial instance used to manage the options on the serial port.

Inherited from FileDescriptor:

Method writeSomeData Write as much as possible of the given data, immediately.
Method doRead Called when data is available for reading.
Method doWrite Called when data can be written.
Method writeConnectionLost Indicates write connection was lost.
Method readConnectionLost Indicates read connection was lost.
Method writeSequence Reliably write a sequence of data.
Method loseConnection Close the connection at the next available opportunity.
Method loseWriteConnection Undocumented
Method stopReading Stop waiting for read availability.
Method stopWriting Stop waiting for write availability.
Method startReading Start waiting for read availability.
Method startWriting Start waiting for write availability.
Method stopConsuming Stop consuming data.
Method resumeProducing Resume producing data.
Method pauseProducing Pause producing data.
Method stopProducing Undocumented
Method fileno File Descriptor number for select().
Method _postLoseConnection Called after a loseConnection(), when all data has been written.
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.

Inherited from _ConsumerMixin (via FileDescriptor):

Instance Variable producer None if no producer is registered, otherwise the registered producer.
Instance Variable producerPaused A flag indicating whether the producer is currently paused. (type: bool or int)
Instance Variable streamingProducer 0 A flag indicating whether the producer was registered as a streaming (ie push) producer or not (ie a pull producer). This will determine whether the consumer may ever need to pause and resume it, or if it can merely call resumeProducing on it when buffer space is available.
Instance Variable streamingProducer bool or int
Method registerProducer Register to receive data from a producer.
Method unregisterProducer Stop consuming data from a producer, without disconnecting.

Inherited from _LogOwner (via FileDescriptor):

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)
overrides twisted.internet.abstract.FileDescriptor.__init__
Undocumented
def _finishPortSetup(self): (source)
Finish setting up the serial port.

This is a separate method to facilitate testing.

def serialReadEvent(self): (source)
Undocumented
def write(self, data): (source)
from twisted.internet.interfaces.IConsumer
overrides twisted.internet.abstract.FileDescriptor.write
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.

def serialWriteEvent(self): (source)
Undocumented
def connectionLost(self, reason): (source)
overrides twisted.internet.abstract.FileDescriptor.connectionLost
Called when the serial port disconnects.

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