I keep getting the Error connecting session: Keyboard is still locked after 10000ms.
However this is true whether I enter a valid host name or not. I have made sure I can ping the server, and that other telnet clients can access it with the same details. Even varied up the TLS and port numbers.
Any suggestions on how to further debug?

how would I enable it then?
Your documentation mentions it.

Would love to pitch this higher up but w/out tn3270E our systems won't work.
