DEFINELIST
DEFINELIST
The DEFINELIST procedure is used only when the application process is acting as a
supervisor or tributary station in a centralized multipoint configuration.
For a supervisor station, a call to DEFINELIST specifies the poll and select addresses of
each tributary station with which the application process wishes to communicate.
For a tributary station, a call to DEFINELIST specifies the poll and select addresses to
which the particular line responds.
The poll and select addresses are in the form of an address list array whose name is
passed to the DEFINELIST procedure by way of the DEFINELIST calling sequence.
The first portion of the address list contains poll addresses, while the remainder of the
list contains select addresses.
The form of the DEFINELIST procedure is:
