{
{
{    The purpose of this request is to propose that a connection to a specified
{ address be opened.  This request will cause delivery of a "connect" event at
{ the destination address.  The user at that address may accept the proposed
{ connection by calling NLP$TA_ACCEPT_CONNECTION.  This will result in an
{ "accept" event being delivered to the event processor specified on the open
{ sap request.  Delivery of the accept event signals that the connection is
{ open and may be used to communicate with the user at the destination address.
{
{    Alternatively, the user at the destination address may reject the proposed
{ connection by calling NLP$TA_DISCONNECT_CONNECTION.  This will result in a
{ "disconnect" event being delivered to the event_processor specified on the
{ open sap request.

{
{ CL_CONNECTION: (input, output)  This parameter specifies the interlayer
{       connection that is to be associated with the transport access agent
{       connection.
{
{ SAP: (input)  This parameter specifies an open service access point over
{       which the connection is to be opened.
{
{ CHECKSUM: (input)  This parameter specifies that data sent and received by
{       transport in the communication device should be checksummed.
{
{ DATA: (input, output)  This parameter specifies data to be delivered at the
{       destination address as part of the "connect" event.  The meaning of
{       this data must be agreed upon by the communicating users.  The length
{       of this data may not exceed 32 bytes.  The system buffers containing
{       this data will be released as a result of this request.
{
{ DESTINATION_TRANSPORT_SAP: (input)  This parameter specifies the service
{       access point to which the connection is to made.
{
{ DESTINATION_NETWORK_ADDRESS: (input)  This parameter specifies the network
{       address to which the connection is to be made.
{
{ CDNA_DESTINATION_ADDRESS: (input)  This parameter specifies whether the
{       destination network address is CDNA or NONCDNA.
{
{ EXPEDITED_DATA: (input)  This parameter specifies whether the transport
{       service provider should allow expedited data requests and indications.
{
{ PRIORITY: (input)  This parameter specifies the priority of the proposed
{       connection.  Zero is the lowest priority and 14 is the highest
{       priority.  A value outside of the zero to 14 range is interpreted as
{       zero.
{
{ PREFERRED_PROTOCOL_CLASS: (input)  This parameter specifies the preferred type
{       of protocol class that is to be used over a transport connection.
{
{ ALTERNATE_PROTOCOL_CLASS: (input)  This parameter specifies the alternate protocol
{       class to be used over a transport connection when the preferred_protocol_class
{       is not available.
{
{       NOTE:  In version 2 of the Transport Protocol, the alternate_protocol_
{              class will ALWAYS be encoded by the Transport Access Agent to
{              be NONE.
{
{ QUALITY_OF_SERVICE (input) This parameter specifies the transport
{       user's requirements.
{
{ STATUS: (output) This parameter specifies the request status.
