SETPARAM Function 3 Procedure
param-count
INT:value
is the number of bytes in param-array. The value for this parameter must be 8.
last-params
INT .ref:1
is the returned previous parameter settings of function passed by reference
(INT .ref:1).
last-params[n]
an integer array containing:
last-params[0]
sets BREAK ownership:
last-params[1]
sets the terminal access mode after BREAK is typed:
last-params[2] and last-params[3]
contains the two words of the 32-bit tag.
last-param-count
INT .ref:1
the number of bytes in the last params array. The value for this parameter must be
8.
Using the SETPARAM function with a function code of 3 simultaneously sets the break
ownership and the value of a 32-bit BREAK tag. When a break is detected, the break
owner receives a BREAK interprocess message containing the BREAK tag. The
purpose of the tag is to support applications that own break on several subdevices at
the same time. Appropriate use of BREAK tags allows such applications to distinguish
between BREAK messages received from any of the subdevices.
0 disable BREAK (default).
1 enable BREAK.
0 normal mode: any type file access is permitted (default).
1 BREAK mode: only BREAK-type file access is permitted.
