OpenEuphoria

It could be that you are using an older version of Euphoria. I've been testing V4.1 and using this program below, it shows that it does reflect the real-time console values - at least on Windows. I'm not using a Unix so I can't comment on that.

include std/console.e 
sequence o, n 
clear_screen() 
o = "" 
n = video_config() 
while 1 do 
   if not equal(o,n) then 
       position(1,1) 
       puts(1, "                                               ") 
       position (1,1) 
       ? n 
       o = n 
   end if 
   n = video_config() 
end while
