{
{ CL_CONNECTION: (input, output)  This parameter specifies the interlayer
{       connection that is to be associated with the TCP Access Agent
{       connection.
{
{ LOCAL_PORT: (input)  This parameter specifies the local port.
{
{ QUEUE_LIMIT: (input)  This parameter specifies the limit on the number of
{       pending connect requests which may be waiting to be accepted by the
{       TCP/IP user.
{
{ SELECTION_CRITERIA: (input)  This parameter specifies the port number and/or
{       the IP address from which the user is willing to receive connect
{       requests.  The TCP protocol layer will discard connect requests
{       received from any other source.  A port number of zero and/or a zero IP
{       address implies that data from all ports and/or IP addresses should be
{       received.
{
{ DEVICE_ID: (input)  This parameter specifies the device identifier through
{       which the connection is to be established.
{
{ CLASS: (input)  This parameter specifies the proposed connection class for
{       the connection.
{
{ STATUS: (output) This parameter specifies the request status.
