{
{      This request allows the calling program to terminate all desired
{ asynchronous activity for a connection without terminating
{ the connection.  All requests that were abnormally terminated by
{ this request will have an error condition of
{ 'rfe$async_req_terminated'.
{
{      Caution should be used when issuing this request, because the
{ results may not be consistent.  The reason for the inconsistencies
{ stems from the inherent nature of the request; attempting to terminate
{ requests that are running asynchronously.  The inconsistent results
{ that the caller may observe:
{
{      1)  Asynchronous requests that were to be terminated by this
{          request could have successfully completed.
{
{      2)  Asynchronous requests that were to be terminated by this
{          request could have failed for a different reason.

{
{ CONNECTION_IDENTIFIER: (input) This parameter specifies the instance
{   of open of the connection file, for which the application wants the
{   specified asynchronous activity(ies) terminated.
{
{ ACTIVITY_TYPES: (input) This parameter specifies the types of
{   activities that should be terminated.  The valid types are
{   send data, receive data and all asynchronous activities.
{
{ STATUS: (output) This parameter returns the results of the request.
{   A status of normal means that all activity of the requested
{   type(s) has been terminated.
