I went back and reviewed correspondence on this list, some by me) around
July 26. Here's a summary.
1. OS6 comes up with mapchan set to IBM something. This is wrong. You need
to null out the mapchan, with
mapchan -n
Then you should be able to display a proper chart of characters, with
those from hex-A0 to hex-FF showing as the ISO 8859-1 character set.
2. With TERM set to at386-ie, you should now be able to run something such
as "setup" or "scoadmin" that uses linedraw characters, and see that they
work.
3. Programs that use terminfo will be able to output the 'smacs'
sequence, then the appropriate character, then 'rmacs'. For instance, try
tput smacs;printf "abcdefghijklmnop";tput rmacs
4. I haven't looked at termcap, and am not in the console right now.
5. If your application programming environment has its own terminal
definition system (doesn't use termcap or terminfo) you may need to create
a new entry for at386-ie. This can get linedraw characters in one of two
ways:
a) switch into graphics mode, output the corresponding characters, and
switch out again, similar to 3 above.
b) output the actual character values of the linedraw characters, which
are in the range of hex-80 to hex-9F.
Hope this helps.
