Connect a TCP or TLS Socket

Demonstrates Socket.Connect, which establishes a TCP connection to a host and port. Setting the TLS argument to _TRUE_ performs a TLS handshake after the TCP connection succeeds.

Background. The hostname may be a DNS name or a numeric IPv4/IPv6 address. The final argument bounds how long the connect attempt waits before failing. On failure, ConnectFailReason and LastErrorText provide detail.
