Consider the versatile s_client tool which comes with openssl.

openssl s_client -connect host:port

Look for Protocol in the output.

Quoting from the manpage
"By default the initial handshake uses a method which should be compatible with all servers and permit them to use SSL v3, SSL v2 or TLS as appropriate."

You can add -ssl2, -ssl3, -tls1, -no_ssl2 etcetera, to enforce a particular protocol (which may fail).
