Test TLS version
(2021-10-06)
If you get cert details back from any of those, the device does support the referenced TLS version.
Problem
Does this device support TLS v1.0 (or 1.1 or 1.2 or 1.3)Solution
$ openssl s_client -connect system:port -tls1 $ openssl s_client -connect system:port -tls1_1 $ openssl s_client -connect system:port -tls1_2 $ openssl s_client -connect system:port -tls1_3

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
