   Taking a look at

https://pubs.opengroup.org/onlinepubs/7908799/xcurses/curses.h.html

   lists the fifteen attr_t constants as (rearranged here to put the 
six 'highlight' attributes together) :

WA_ALTCHARSET  Alternate character set
WA_BLINK       Blinking
WA_BOLD        Extra bright or bold
WA_DIM         Half bright
WA_INVIS       Invisible
WA_PROTECT     Protected
WA_REVERSE     Reverse video
WA_STANDOUT    Best highlighting mode of the terminal
WA_UNDERLINE   Underlining

WA_LEFT        Left highlight
WA_RIGHT       Right highlight
WA_LOW         Low highlight
WA_TOP         Top highlight
WA_HORIZONTAL  Horizontal highlight
WA_VERTICAL    Vertical highlight

   which suggests to me that A_LOW isn't A_DIM and it isn't 
A_UNDERLINE.  I'd think the six 'highlight' attributes would be similar, 
 except that they 'highlight' different parts of the character cell.

   Dennis,  that terminal is probably gradually transitioning from "old 
obsolete stuff" to "valued piece of historical computing equipment",  if 
it's not there already.  I'm curious about what you see on it,  too.
