If your site runs port scans against your z/VM 5.2 SSLSERV, you might
get notes from the network people saying you are running an old 2.0
version of SSL.

In z/VM 5.2 you can use SSL with FTP and TN3270, or any other protocol, 
provided your client supports the model of "Establish the SSL tunnel
first 
and the flow the protocol over it" (a la https).  We call that "static"
or 
"transparent" SSL.

In z/VM 5.3 you do those same things, but you can also use clients that 
negotiate the use of SSL over the traditionally unsecured port.
Further, 
you can add SMTP and client-side (CMS) FTP and TELNET command support to

the list.

IBM Personal Communications 5.9 is an example of a TN3270 client that 
supports both kinds of secure telnet.
