BREAK, cont'd.
Chapter 2 Program Instructions
Remarks, cont'd. A specified break interrupt character is saved in the temporary memory until
the printer is restarted or REBOOTed, which may be confusing e.g. when
changing between programs. To change a break interrupt character, specify
a new one for the same device using a BREAK statement and to remove it
from memory, use a BREAK OFF statement.
The use of break interrupt is enabled or disabled separately for each device
by BREAK ON or BREAK OFF statements. By default, break interrupt on
the "console:" is enabled, while break interrupt on any of the communication
channels is disabled.
It is strongly recommended to include some facility for issuing a break
interrupt from the host computer in startup (autoexec) files. If not, you may
find yourself with an erroneous program running in a loop without being able
to break it!
Examples In this example, the ASCII character 127 decimal is selected and enabled as
BREAK character on the communication channel "uart1:":
10 BREAK 1,127
20 BREAK 1 ON
.....
.....
.....
In next example, BREAK characters are specified for both the keyboard
("console:") and the serial communication channel "uart1:". The loop can
be interrupted either by pressing the key usually marked “F1” on the printer's
keyboard, or by typing an uppercase X on the keyboard of the host:
10 BREAK 0,1:BREAK 1,88
20 BREAK 0 ON:BREAK 1 ON
30 GOTO 30
RUN
Reset BREAK to default by turning the printer off and on.
In the Intermec Direct Protocol or the Immediate Mode, you can break the
printing of a batch of labels. This example shows how the key on
the printer's built-in keyboard is used for that purpose:
BREAK 0,30:BREAK 0 ON:FT "Swiss 721 BT":
PT"HELLO":PF 10 ↵
