I would agree that it would be great if tcsetattr(NOECHO) actually worked under 3270 OMVS shells.
But, under a TSO OMVS 3270 shell, using HOS1130 or HOS2220, don't you get this: ? zos$ ssh -oPubKeyAuthentication=no 127.0.0.1 FOTS3322 Passwords may not be entered from 3270 terminals (terminates) But the above behavior is still a big improvement: you can now do basic connectivity tests and anything else as long as you don't need to prompt for a password. So keys work fine.
