`SocketConnect`¶

Opens the near end of an outgoing TCP connection. The endpoint may be a port, a "host:port" string, a host and a port, or a {host, port} pair.

$ wo 'srv = SocketOpen[0]; Head[SocketConnect[srv["DestinationPort"]]]'
SocketObject

$ wo 'srv = SocketOpen[0]; port = srv["DestinationPort"]; SocketConnect["127.0.0.1:" <> ToString[port]]["DestinationPort"] == port'
True

A connection describes itself as a client, not a server:

$ wo 'srv = SocketOpen[0]; SocketConnect[srv["DestinationPort"]]["DirectionType"]'
Client
