(c)dialog working differently during boot in script called by rc system than after boot?

[Robarrght]

Thank you, Dan.  That was exactly what I was missing.
I added:

    export TERM=cons25

to the rc.d script and now my script works as it should, when I want
it to do so.

I appreciate your help, very much!
