Hey, I also have a FreeBSD 14.2, but I also have a FreeBSD 14.1.  It
turns out the problem does not happen on the FreeBSD 14.2:

$ echo $TERM
xterm

$ uname -a
FreeBSD b 14.2-RC1 FreeBSD 14.2-RC1 releng/14.2-n269505-5395ddd7aa13 GENERIC amd64

$ sbcl
This is SBCL 2.4.9, an implementation of ANSI Common Lisp.
More information about SBCL is available at <http://www.sbcl.org/>.

SBCL is free software, provided as is, with absolutely no warranty.
It is mostly in the public domain; some portions are provided under
BSD-style licenses.  See the CREDITS and COPYING files in the
distribution for more information.
* (format t "hello~%")
hello
NIL
*

But, as you know already, here's what happens on FreeBSD 14.1:

$ echo $TERM
xterm

$ uname -a
FreeBSD my.domain 14.1-RELEASE-p5 FreeBSD 14.1-RELEASE-p5 GENERIC amd64

$ sbcl
This is SBCL 2.4.9, an implementation of ANSI Common Lisp.
More information about SBCL is available at <http://www.sbcl.org/>.

SBCL is free software, provided as is, with absolutely no warranty.
It is mostly in the public domain; some portions are provided under
BSD-style licenses.  See the CREDITS and COPYING files in the
distribution for more information.
* (format t "hello~%")
hello
NIL
*

What?  It stopped doing it.  What in the world is going on?  This was
not a on-and-off thing; it was always doing it.  I did not even set
anything new on my PuTTY configuration or anything.  I'm very puzzled
now.
