Summary Request
The summary request PDU command permits an application program to request
a summary of the exchanges configured on a given node. This allows a user to
get a complete list of all exchanges defined. The Index field is normally 0 and is
used to request a block of summaries in nodes which contain a large number of
exchanges. A summary request sent from a requesting node must be followed by
a summary response message from the responding node.
