2.1.1. Defining Temporary Escape Character
No ESC character is defined when you receive the converter. If you
wish to change the settings from the host system, you will have to
define the ESC character . See below how to define "%" as the tem-
porary ESC character .
NOTE:
The characters "," ";" and ":" must never be used as
ESC character s, as they are used as separators in
escape sequences and will give unpredictable printing
results.
The same applies to 0-9, A-F, a-f and K,S,T,X,Y,Z,
simple quote ('), & and ?. These must not be used.
CAUTION !
Avoid using your national characters as ESC characters.
The following EBCDIC HEX codes have been defined as
national language characters and must not be used as ESC
characters.
4A 4C 4F 5A 5B 5F 6A 79 7B 7C 7F A1 C0 D0 E0
Defining "%" as a temporary ESC character .
The five characters shown should be sent to the printer from the host
system. The ESC character is not defined perma nently. When the
converter is turned off, it will be lost. See "Defining a Permanent Es-
cape Character" for infor mation on the definition of a permanent
ESC character .
