{   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.

{ SAP_TIMER_EVALUATOR: (input) This parameter specifies a procedure in the
{       requestor's layer to be called periodically to evaluate timers.
{
{   NOTE: SAP_TIMER_EVALUATOR must be invariant on a connection path.
{         That is, the requesting layer's timer procedure must be the
{         same for all open sap requests.
{
{ 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.
