    listener ID in

    A network connection refnum that uniquely identifies the listener.

    resolve remote address

    Boolean that indicates whether to call the IP Address to String node on the remote address. Refer to IP Address to String for more information.

    True The node calls the IP Address to String node on the remote address.
    False The node does not call the IP Address to String node on the remote address.

    Default: True

    timeout ms

    Time, in milliseconds, that the node waits for a connection. If the node cannot establish a connection in the specified time, the node returns an error.

    Default: -1 — Causes this node to wait indefinitely for a connection.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    listener ID out

    The same network connection refnum as listener ID in. Use this value to refer to the listener in subsequent calls to this node.

    datatype_icon

    remote address

    The address of the remote machine associated with the TCP connection.

    datatype_icon

    remote port

    The port the remote system uses for the connection.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    connection ID

    A network connection refnum that uniquely identifies the connection. Use this value to refer to this connection in subsequent node calls.
