There is no magic switch. The output comes from the ckcfns.c nxtdir()
function and it clearly outputs everything with only a "\n" as the
terminator. This is true for C-Kermit and Kermit 95. Now in the case
of MS-DOS Kermit connected to C-Kermit via a tty, the pseudoterminal
may expand the LF into CR-LF. This is not the result of anything that
C-Kermit is doing. If you were to connect MS-DOS Kermit to C-Kermit
over a raw connection, you would see the same behavior.
In the case of MS-DOS Kermit to Kermit over TCP/IP, you may very well
see different behavior because the newline in NVT mode would be
converted to CR-LF.
It is only over a serial connection that you would see the raw LF.
If someone is interested in a build of Kermit 95 that performs
this expansion, they can read the information available at
http://www.columbia.edu/~jaltman/
and hire me to make the change.
