TAKE^BREAK Procedure
Although the operating system allows a process to own BREAK on an arbitrary
number of terminals, SIO supports BREAK ownership for only one terminal at a
time.
•
SIO does not support “break access”; SIO always issues SETMODE 11 with
parameter 2 = 0.
•
Taking BREAK ownership back
If a process launches an offspring process that takes BREAK ownership, and the
parent process then calls CHECK^BREAK, SIO takes BREAK ownership back.
This can affect anticipated handling of BREAK.
Example
CALL TAKE^BREAK ( OUT^FILE );
