If a negotiation regarding this option is already in progress, the Deferred will fail with L{AlreadyNegotiating}.

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. @ivar 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. @ivar 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. @ivar 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. @ivar transport: This protocol's transport object. rG c C s. i | _ i | _t| jt| jt| jt| j i| _ d S rj ) �options�negotiationMap�WILL� telnet_WILL�WONT� telnet_WONT�DO� telnet_DO�DONT� telnet_DONT� commandMaprb rB rB rE �__init__� s �zTelnet.__init__c C s | j �|� d S rj �� transport�write�rc rG rB rB rE �_write� s z Telnet._writec @ s. e Zd ZdZG dd� d�Zdd� Zdd� ZdS ) zTelnet._OptionStatea Represents the state of an option on both sides of a telnet connection. @ivar us: The state of the option on this side of the connection. @ivar him: The state of the option on the other side of the connection. c @ s$ e Zd ZdZdZdZdZdd� ZdS )z Telnet._OptionState._Perspectivea� Represents the state of an option on side of the telnet connection.
