This block supports TCP connections in both server (listening for inbound connections) and client mode (initiating connections to other systems as a client). In client mode,the block connects to a server at the given address and port. In server mode, the block starts a local listener on the given port and accepts the first client connection.

This block does support IPv6 addresses. If an IPv6 address is detected as the destination IP address, the block will automatically adjust for proper connection. Just make sure your IPv6 stack is enabled. To listen in server mode for both IPv4 and IPv6, use :: as the address. To connect to IPv6 localhost use ::1 as the address.
