160 Universal Control Commands
STORING DOWNLOAD CHARACTERS
Download characters are stored in RAM (temporary memory). The
character currently mapped to the same data byte value in ROM
(permanent memory) is not overwritten. Characters that have not been
downloaded, mapped, or overlayed print from the currently selected
character set stored in ROM. (See the next subsection, "Printing
Downloaded Characters".) If you select another character set or change
emulation mode, your downloaded characters are not overwritten.
Downloaded characters remain in temporary memory, RAM, until:
•
Cleared with the "Factory Reset" option on the configuration menu or
with control command SOH AzX
•
Overwritten with other selections
•
Cleared by setting the "Input Buffer Size" option to "Maximum (no
user-defined characters)" or by setting the "Overlay Characters" option
to "None"
•
Power is turned off
Note:
Download characters may be retained for a variable amount of time
after the power is turned off.
