As has already been described by other posters, the SCO "man" command
clobbers the TERM environment variable when running the pager of
choice.

I fixed it locally by (1) creating /u/local/bin/man which is in the
search path first, which sets the environment variable REALTERM to the
value of TERM before running /usr/bin/man, (2) in /etc/default/man
setting PAGER=/usr/man/bin/less-term, and (3) in the less-term script,
setting TERM from REALTERM.  As a bonus, if REALTERM is not set, it
checks the terminal type in /etc/ttytype.

Here is the less-term script.  Shar and enjoy.

#! /bin/sh
# This is a shell archive.  Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file".  To overwrite existing
# files, type "sh file -c".  You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
#		"End of shell archive."
