Public Methods
 Abort | Abort any blocking method and release all system resources. |
| About | Show the About Box. |
| ClearCertificate | Clears the Certificate Property |
| Close | Close the session and release all system resources. A single control can be used for many connections, one after the other. |
| Connect | Establish a secure connection. The State property immediately changes to tcpConnecting and changes to tcpConnected when the connection is established, the security protocol is negotiated and authentication succeeds. The State property can be checked in the body of the State Event, polled off a timer, or checked immediately after this method is used when a positive Timeout is specified. |
| Fill | Use this method when you know exactly how many bytes or characters you want from the TCP stream. Data is either filled to capacity or no data is returned. This method is useful for processing fixed-length records that can include binary structures. |
| Receive | Receive an arbitrary amount of data. The specified String or Byte array is filled with bytes from the remote host. |
| Search | Receive data up to and including a terminating sequence. The data stream is searched for the specified Token, and the specified string, byte array, or DartStream object is filled with the data stream up to and including the specified Token. This method is useful for processing variable-length records or lines that are defined by known delimiter strings. |
| Send | Send data after a connection is established. The Send event fires when data is accepted by the system. The SendBufferCount property always indicates the number of bytes that have been submitted but have not yet been accepted by the system. |
| Trace | Start or stop the accumulation of trace or debug data. Once started, this method accumulates data until it is turned off. This method provides a convenient mechanism for viewing all data being sent and received over the connection and can be used to troubleshoot host interoperability issues and expose protocol communications. |
Public Properties
 Blocked | A True value indicates the control is currently executing a blocking method (Timeout is greater than 0), which has neither completed nor timed out with a ptTimeout error. |
| Certificate | Certificate Object to use when authenticating to the remote host |
| ClientAuthentication | Request that the client authenticate itself, only applies to server operation. |
| IpV6 | Specifies whether hostname addresses should be favorably resolved to IPv6. |
| KeepAlive | When set to True, the KEEPALIVE socket option is set to monitor dropped connections. This option can only be set when the State property is tcpConnected. |
| LocalAddress | When the State property is tcpConnected, returns the IP address of the local host. When not connected, returns an empty string. |
| LocalPort | When the State property is tcpConnected, returns the port number that the socket is bound to. When not connected, returns 0. |
| NoDelay | When True, the NODELAY socket option is set to defeat Nagle's algorithm. |
| Protocol | Specifies the security protocol used. |
| ProxyHost | Specifies the name or address of the proxy server that requests are to be routed through. |
| ProxyPassword | Password to be sent on all requests through a proxy server that requires authentication. |
| ProxyPort | Specifies the port used by proxy server that requests are to be routed through. |
| ProxyType | The type of proxy server used for this connection. |
| ProxyUsername | Username to be sent on all requests through a proxy server that requires authentication. |
| ReceiveBufferCount | The number of bytes available for receiving. |
| ReceiveBufferSize | Number of bytes the system has for buffering incoming data. |
| Ref | Stores a reference to another object, data type, or value. |
| RemoteAddress | Returns the IP address of the remote host when the State property is tcpConnected. |
| RemoteCertificate | Contains certificate credentials provided by remote host |
| RemotePort | Returns the port number of the remote host when the State property is tcpConnected. |
| ReuseAddress | When True, the REUSEADDR socket option is set to accept duplicate use of the same LocalAddress / LocalPort pair (these are optional parameters of the Connect and Listen methods). If used, this property must be set prior to calling the Connect or Listen method and can be set at design time. |
| Security | Sets the security level during communication. |
| SendBufferCount | When the Send method is used, some data may be stored in a buffer and later submitted to the system. The Send event fires to indicate that the system has accepted the submitted data. |
| SendBufferSize | Number of bytes the system uses for buffering outgoing data. |
| SessionName | Used to control session caching when consecutive secure connections are made to the same server. |
| Socket | System identifier assigned to the TCP connection. It is normally used to assume management of a socket accepted from the Daemon Control. |
| State | Provides status information to the user interface. The State event fires to signal that this property has changed. |
| Timeout | Controls the blocking behavior of methods that can be used in blocking and non-blocking ways. |
| UseSslShutdown | Specifies use of SSL Shutdown handshaking before closing. |
Events
 Authenticate | Fires when the remote host has sent a certificate to be authenticated. |
| Certificate | Fires when the remote host is requesting a certificate and the Certificate property is not set to a valid Certificate Object. |
| Error | Fires when an error condition occurs. |
| Receive | Fires when ReceiveBufferCount changes. |
| Send | Fires when the system accepts data for sending. |
| State | The State Property has changed |
