Tony,

You need to do a TCPIP command to stop and then start the TN3270 port number 
using the new cert. 

Thank you.

Can you get into line-mode UNIX? SSH or (sigh) telnet?

What about line-mode TSO?

If these ports are open it seems unlikely they'd be secured with the same SSL 
cert. Maybe they're not secured at all...
