(View In Hierarchy)
A select()able serial device, acting as a transport.
Method | __init__ | |
Method | fileno | File Descriptor number for select(). |
Method | writeSomeData | Write some data to the serial device. |
Method | doRead | Some data's readable from serial device. |
Method | connectionLost | Called when the serial port disconnects. |
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 | doWrite | Called when data can be written. |
Method | writeConnectionLost | Indicates write connection was lost. |
Method | readConnectionLost | Indicates read connection was lost. |
Method | write | Reliably write some data. |
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 | Stop producing data. |
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 ) |
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. |
Parameters | reactor | An 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. |
File Descriptor number for select().
This method must be overridden or assigned in subclasses to indicate a valid file descriptor for the operating system.
Called when the serial port disconnects.
Will call connectionLost
on the protocol that is handling
the serial data.
