Selects the character set to be used. Look in “Appendix B: Resident Character Sets” in the A799 User Guide Programming 

Supplement for the character sets.
There are two codes for this command (See “Select international character code, 1B 52 n.) Both codes perform the same 
function.

The LEGACY emulation selection applies only to the command “Select international character code” (1B 52 n).   
The LEGACY emulation generates the same as A799 native mode for the command “Select international character set” 
(1B 74 n).

ESC { n 

Hexadecimal  1B 7B n

Value of n:

1 = Set

0 (Cancel)

Prints upside-down characters. The command may be combined with clockwise rotated print (1B 56) or counter-clockwise 
rotated print (1B 12). The character order is inverted in the buffer so text is readable. Only bit 0 is used. Bits 1-7 are not 
used. See summary of rotated printing in this document for more information.

The command is valid only at the beginning of a line.
It cannot be used with right side up characters on the same line.
