Known subclasses: twisted.conch.telnet.TelnetTransport

Instance Variable commandMap A mapping of bytes to callables. When a telnet command is received, the command byte (the first byte after IAC) is looked up in this dictionary. If a callable is found, it is invoked with the argument of the command, or None if the command takes no argument. Values should be added to this dictionary if commands wish to be handled. By default, only WILL, WONT, DO, and DONT are handled. These should not be overridden, as this class handles them correctly and provides an API for interacting with them.
Instance Variable negotiationMap A mapping of bytes to callables. When a subnegotiation command is received, the command byte (the first byte after SB) is looked up in this dictionary. If a callable is found, it is invoked with the argument of the subnegotiation. Values should be added to this dictionary if subnegotiations are to be handled. By default, no values are handled.
Instance Variable options A mapping of option bytes to their current state. This state is likely of little use to user code. Changes should not be made to it.
Instance Variable state A string indicating the current parse state. It can take on the values "data", "escaped", "command", "newline", "subnegotiation", and "subnegotiation-escaped". Changes should not be made to it.
Instance Variable transport This protocol's transport object.

def requestNegotiation(self, about, data): (source)

Send a negotiation message for the option about with data as the payload.

Parametersdatathe payload (type: bytes)
See AlsoITelnetTransport.requestNegotiation
def dataReceived(self, data): (source)

Called whenever data is received.

Use this method to translate to a higher-level message. Usually, some callback will be made upon the receipt of each complete protocol message.

Parametersdataa string of indeterminate length. Please keep in mind that you will probably need to buffer some data, as partial (or multiple) protocol messages may be received! I recommend that unit tests for protocols call through to this method with differing chunk sizes, down to one byte at a time.
def connectionLost(self, reason): (source)

Called when the connection is shut down.

Clear any circular references here, and any external references to this Protocol. The connection has been closed.

def applicationDataReceived(self, data): (source)

Called with application-level data.

def enableLocal(self, option): (source)

Reject all attempts to enable options.

def enableRemote(self, option): (source)

Reject all attempts to enable options.

def disableLocal(self, option): (source)

Signal a programming error by raising an exception.

enableLocal must return true for the given value of option in order for this method to be called. If a subclass of Telnet overrides enableLocal to allow certain options to be enabled, it must also override disableLocal to disable those options.

RaisesNotImplementedErrorAlways raised.
def disableRemote(self, option): (source)

Signal a programming error by raising an exception.

enableRemote must return true for the given value of option in order for this method to be called. If a subclass of Telnet overrides enableRemote to allow certain options to be enabled, it must also override disableRemote tto disable those options.
