No, that is an indication that port 22 is not open.
Actually, it looks like you did a telnet to the (default) telnet port
(23):
telnet 192.168.1.12
rather than the ssh port (22), as Ed suggested:
telnet 192.168.1.12 22
which is what is needed to get meaningful results.
Try the telnet to the ssh port and see what you get. It may be a
firewall issue, but the results you showed don't appear to be a test
of the issue.
