WARNING: terminal is not fully functional

Been getting the message on SCO Openserver 5.0.7
I have begun the process of creating new users on the server. The shell that we use is /bin/csh. The user creation process seems fine. When the user logs in and types the list command (“l”), he gets this message “WARNING: terminal is not fully functional” prior to the command executing.
This took me a bit to figure out. We are using dosansi as the terminal type. In the .csh startup file there is a line containing the following (which I think sets it to dosansi):

Setenv TERM dosansi

I think we need this terminal type in the custom software that we run. The error described below also happens when you try to use the “man” command.

Any Help or suggestions would be greatfull.
