command to “normalize” the high-order control codes is (ESC)
“6”. Try this program with the DIP switch 1-6 on.

When you run this program you’ll get like this:
That’s where the italic international characters have been
stored. So the (ESC)“G” command without the (ESC)“R” gives
you access to the international characters. The (ESC)“7” turns
these characters back into control codes.
The low-order control codes can also be defined, but not all of
them can be printed with ease. The (ESC)“I” 1 command
makes them printable, and the (ESC)“I”O command returns
them normal.
Just as the higher control codes hide the italic international
characters, the lower control codes hide the roman international
characters.
Let’s see how these commands work with the following pro-
gram:
