BREAK, cont.
Remarks, cont. A specifi ed break interrupt character is saved in the temporary memory until
the printer is restarted or REBOOTed, which may be confusing for example
when switching 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) fi les. If not, you
may fi nd 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 specifi ed 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.
