     If by "Asian (16-bit) codes" you are referring to the Japanese
Industrial Standard (JIS) character set, this is a 14-bit character
set and not a 16 bit one.  Also, it only uses the code values which
have printable representations in ASCII.  That is, the lowest value
of either byte is 21h and the highest value is 7Eh.  The first JIS
character, a blank, is therefore 2121h.  The last JIS character is
717Eh and is a level 2 kanji ("level 1" are the commonly-used chinese
characters (kanji), "level 2" are much more rare and most native
Japanese only know a few).  There are holes in the character set as
well.

     How are shift-in and shift-out effected?  I'm aware of at least
5 ways this can be done!
