Correct. None of the Kermit programs includes 3270 emulation yet.

You can get a fullscreen connection from any of these Kermit programs by
making an intermediate connection to a 3270 protocol converter. Examples:
. Dial up to a protocol converter such as an IBM 7171.
. Telnet to a terminal server that supports tn3270, such as most Ciscos.
. Telnet to a host that has a tn3270 program.
. In C-Kermit 7.0, give the command "pty tn3270 hostname".

:
Most Unix hosts have a tn3270 program. Most terminal servers have a
tn3270 command. As for dedicated physical boxes such as 7171s, you have
to know about them in advance.
