control char in unix

Comes out in boldface on my machine.  You probably set SunView up (or
XView, if you're running X) so that the tty subwindow (e.g.,
"shelltool") maps the boldface enhancement to inverse video (since you
say you have 4.x, whose tty subwindow code supports boldface, inverse
video, and underline). 

>PS1='

You mean

	PS1="

etc., because the Bourne shell doesn't expand variables in strings
enclosed in single quotes, just strings enclosed in double quotes.

You do, but you can just embed the escape sequences, as you note later;
"tput bold" just pumps out "<ESC>[1m", for example.
