xserver on CURRENT, two xterms, each running current bash etc.
o one to a bsdi 3.1 system (same on sunos, ...)
o one to the same freebsd host
say 'less foo' (or vi foo, or ...)
o quit less on bsdi and the screen is restored. i.e., you see
foo% more iddd.patch
foo%
i.e. all the remnants of less's output are gone, and the screen is
restored exactly as it was before the command ran, with a new prompt
right below the one that issued the command, even if it is mid-screen.
o after running less on freebsd the screen is not restored. i.e. the
remnants of less fill the screen with the new prompt on the bottom
line of the xterm, and the previous prompt and screen obliterated.
i prefer the former behavior, but do not understand how to cause the freebsd
system to adopt it.
looking at stty parms, the only differences are as follows:
bsdi
oflags: opost onlcr oxtabs
^^^^^^
cflags: cread cs8 -parenb -parodd hupcl -clocal -noclocal -cstopb
^^^^^^^^^
-cts_oflow -rts_iflow -mdmbuf
^^^^^^^^^^^^^^^^^^^^^
freebsd
oflags: opost onlcr -oxtabs
^^^^^^^
cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb
-crtscts -dsrflow -dtrflow -mdmbuf
^^^^^^^^^^^^^^^^^^^^^^^^^^
nothing tasty there. how about termcap?

but
o replacing freebsd's with bsdi's (noting the te/ti)
o rebuilding termcap.db
o and starting a new xterm
gives me the same result.
any clues?
