I believe that requires an ssh *server* on the workstation. Until recently,
I was able to run sshd under Cygwin on my employer's PC. Not lately;
I suspect someone tightened security rules.

Even so, isn't forwarding being done on localhost which makes an unsecured
connection to myzosbox:23, which may not meet the requirement?

When I try remote forwarding with the -R option, which should make
a secured connection, I get:
Warning: remote port forwarding failed for listen port 12345

I assume there's some unstated requirement to get to the TSO READY
