{
{    The purpose of this procedure is to access the global structure for the
{ listen socket corresponding to the given application name, port number and
{ the bound address to check if there is a received socket waiting to be
{ accepted.  If there are no received sockets and wait is TRUE, the current
{ task is queued in the wait for socket list.  The task is readied and dequeued
{ on receipt of an accept socket.

{
{ APPLICATION: (input)  This parameter specifies the application name.
{
{ PORT: (input)  This parameter specifies the port number to which the listen
{       socket is bound.
{
{ BOUND_ADDRESS: (input)  This parameter specifies the IP address to which the
{       listen socket is bound.
{
{ WAIT: (input)  This parameter specifies whether the caller would like to wait
{       for an accept socket.
{
{ ACTIVITY_COMPLETE: (output) This parameter is set to TRUE if an accept socket
