Hi.  Sorry to jump in to the middle of this conversation.
You seem to think that vim will run on a dumb terminal. I am fairly
certain that it will not run on a dumb terminal.
For example, this error indicates that you are attempting to run vim
using a terminal that doesn't contain the "cm" capability.  Vim will
refuse to run if your terminal does not have a "cm" capability.
The "cm" capability is termcap name of the "cursor address" capability,
which is the capability to move the cursor to a given row and column on
the screen.
If your terminal can move to a given row and column, it is, by
definition, not a dumb terminal.
So, I believe you are trying to do is not going to work.
I think what you are actually trying to accomplish is to print
a message with a white text on a red background.  And, for some
reason, you don't want to specify a particular terminal.
A short, ugly way to accomplish this is directly to use the SGR ANSI
color escape sequence.  This works on many color terminals.
echo "\033[37;41mHello World"
Hope this helps,
Mike Gran
