{
{    The purpose of this request is to send expedited data over an open
{ connection.  This request will cause delivery of an "expedited data" event to
{ the user at the other end of the connection.  Expedited data is not subject
{ to flow control and may be delivered at the other end of the connection ahead
{ of normal data which was sent earlier.  The expedited data request must be
{ confirmed by the transport service provider in the communication device.  The
{ transport access agent will allow two unconfirmed expedited data requests to
{ be outstanding.  The assumption is that the communication device has
{ confirmed the requests but the actual confirmation pdu has not yet been
{ received.  The fact that a previous request has been confirmed is not
{ conveyed to the user.

{
{ CL_CONNECTION: (input, output)  This parameter specifies the interlayer

{       connection on which the expedited data is to be sent.
{
{ DATA: (input, output)  This parameter specifies data to be included as part
{       of the "expedited data" event.  The length of this data may not exceed
{       16 bytes.  The system buffers containing this data will be released as
{       a result of this request.
