{   The purpose of this request is to provide configuration information about a
{ particular channel.
{
{       CMP$GET_CHANNEL_DEFINITION (CHANNEL_IDENTIFICATION, CHANNEL_DEFINITION,
{         STATUS)
{
{ CHANNEL_IDENTIFICATION: (input)  This parameter specifies the identity of the
{       channel whose configuration information is sought.  Either the name of
{       the channel or the physical address of the channel may be used to
{       identify it.
{
{       If the mainframe has more than one IOU the name of the IOU must be
{       initialized in the field of this parameter because channel numbers are
{       ambiguous in a multi-IOU system.  The IOU component of this parameter
{       will be ignored on single IOU mainframes.
{
{       If you do not use logical identification to identify the channel, then
{       the CONCURRENT field must be initialized to avoid ambiguity; some IOUs
{       have both concurrent (CIO) channels and non-concurrent (NIO) channels
{       with the same number.
{
{ CHANNEL_DEFINITION: (output)  This parameter specifies the configuration of
{       the channel.  If a channel name is specified in the
{       CHANNEL_IDENTIFICATION , then the CHANNEL_DEFINITION will include which
{       channel port was specified, if any; if no port was specified, then
{       cmc$unspecified_port is returned.
{
{ STATUS: (output) This parameter specifies the request status.
