classdef TPTxState % TPTxState Enumeration class for J1939 transport protocol transmit state. % % This class defines an enumeration which is the possible states for the % J1939 transport protocol transmit activity for a J1939 channel. % Authors: Jaremy Pyle % Copyright 2015 The MathWorks, Inc. enumeration % Inactive - Transmitter is initialized, but not yet actively sending. Inactive % WaitingForCTS - Transmitter is waiting for Clear To Send from the % receiver. WaitingForCTS % WaitingForAck - Transmitter is waiting for an Acknowledgment from the % receiver. WaitingForAck % SendingDT - Transmitter is actively sending Data Transfer messages. SendingDT % DTDelayed - Data transfer has been delayed by the receiver via flow % control messaging. DTDelayed % Completed - Data transfer is completed and acknowledged by the % receiver. Completed % Aborted - Data transfer has been cancelled by the receiver. Aborted % TimedOut - Transmitter activity has timed out waiting for flow % control from the receiver that did not arrive. TimedOut end end
