Semigraphics on unsupported terminal

ITEM: RTA000077245

I've been trying to configure a terminfo entry for an unsupported               
norwegian terminal called tdv1200. This is a 7-bit ascii terminal.              
I found the "graphic mode ON / OFF" sequences and inserted them                 
in the smacs/rmacs entries. I also found all 11 characters for                  
the box1 entry. They were all below 0x7F.                                       
                                                                                
Using "tput smacs ; tput box1; tput rmacs" resulted in the same 11              
semigraphic characters that was output using an hft.                            
                                                                                
Starting ascii-info gave beutiful boxes, but starting SMIT gave only            
the character representation of the box i.e. at if smacs and rmacs did          
not work.                                                                       
                                                                                
I've seen one instance on SETI where info did not work and where smit           
did                                                                            
.The explanation then could be that InfoExplorer was using 8-bit                
and SMIT was using only 7-bit.  Here I see the opposite : My terminal           
is using 7 bits and works with the 8-bit InfoExplorer but not with the          
7-bit SMIT ......                                                               
                                                                                
How can I get boxes in SMIT ???                                                 
Can you give me a clue as to what I should keep on searching for ?              
                                                                                
                                                                                
ANSWER                                                                          
                                                                                
Both SMIT and InfoExplorer use terminfo to determine the terminal               
function/capability. InfoExplorer is using curses/extended curses to            
control the screen. SMIT uses its own set of screen handling routines.          
InfoExplorer uses the first 6 chracters defined for the box whereas            
SMIT requires all 11 characters defined for the box.                            
Sometimes a terminal has to change fonts to be able to print the box            
characters. Then you need the font0, font1, and batt1 attributes.               
Specifying "batt1=f1" indicates that the font1 character set is needed          
to draw the boxes. font0 specifies the code to restore the terminal             
to the original character set.                                                  
box1, batt1, font0, font1 are AIX-unique implementations. System V UNIX         
uses acsc to specify the characters, and smacs and rmacs starts and             
stops the alternate character set.
