{
{   The purpose of this request is to establish access to a service access
{ point.  Requests to open connections may be sent and received over the
{ opened service access point.

{           ACCEPT_CONNECT_EVENTS, MAXIMUM_ACTIVE_CONNECTIONS, SAP_PRIORITY,
{           RESERVED_SAP, SAP, STATUS)
{
{ SAP_PROCESSOR: (input) This parameter specifies a procedure in the requestor's
{       layer to be called to accept delivery of connect events occurring on
{       the service access point which is to be opened.  This procedure will
{       always be called in a NAM/VE system task.  If this is not an appropriate
{       task for processing the delivered event, then it is the responsibility
{       of the procedure to switch processing to an appropriate task.
{
{ CONNECTION_PROCESSOR: (input) This parameter specifies a procedure in the
{       requestor's layer to be called to accept delivery of connection events
{       occurring on the service access point.  This procedure may be called in
{       any task.  If the called task is not an appropriate task for processing
{       the delivered event, then it is the responsibility of the procedure to
{       switch processing to an appropriate task.
{
{   NOTE: SAP_PROCESSOR and CONNECTION_PROCESSOR must be invariant on a
{         connection path defined by APPLICATION_LAYER.  That is, the
{         requesting layer's processor procedures must be the same for all
{         open sap requests.
{
{ APPLICATION_LAYER: (input) This parameter specifies the application layer
{       that is ultimate user of the service access ponit.
{
{ ACCEPT_CONNECT_EVENTS: (input) This parameter specifies whether the requestor
{       is willing to accept connect events from a peer.  If the requestor is
{       unwilling to accept connect events, the peer connect request is
{       rejected.
{
{ MAXIMUM_ACTIVE_CONNECTIONS: (input) This parameter specifies the maximum
{       number of connections that can be established on the service access
{       point.  Attempts to establish a connection which would cause this
{       value to be exceeded are rejected.
{
{ STATUS: (output) This parameter specifies the request status.
