List configuration descriptions & Search hardware resource entry


     ** Program     : CBX101
     ** Description : Returns the name of the line currently holding the ECS modem
     **
     **  Program summary
     **  ---------------
     **
     **  Configuration API:
     **    QDCLCFGD      List configuration    Returns a list of configuration
     **                  descriptions          descriptions based on type as
     **                                        well as selection criterias such
     **                                        as status and category.
     **
     **  User space APIs:
     **    QUSCRTUS      Create user space     Creates a user space.
     **
     **    QUSPTRUS      Retrieve pointer to   Returns a pointer to the contents
     **                  user space            of a user space. The data pointed
     **                                        to can be directly modified by
     **                                        the program obtaining the pointer.
     **
     **    QUSDLTUS      Delete user space     Deletes a user space.
     **
     **  Message handling API:
     **    QMHSNDPM      Send program message  Sends a message to a program stack
     **                                        entry (current, previous, etc.) or
     **                                        the joblog.
     **
     **  Hardware resource API:
     **    QRZSCHE       Search hardware       Searches the hardware resources
     **                  resource entry        for entries matching the request
     **                                        criteria(s) in the form of key
     **                                        values. Upon a succesful search
     **                                        the first or next resource name
     **                                        found is returned.
     **
     **  Sequence of events:
     **    1. Create user space
     **
     **    2. List configuration description(s) selected
     **       based on the return value from the GetEscRsc()
     **       procedure to user space
     **
     **    3. Retrieve the configuration description(s)
     **       one by one.
     **
     **    4. Send completion message to inform caller
     **       what line - if any - is currently allocating
     **       the ECS resource.
     **
     **    5. Delete user space.
     **
     **
     **  GetEscRsc() parameters:
     **    Return-     OUTPUT     The name of electronic-customer-support
     **    value                  communications resource is returned.
     **
     **                           If no matching entry was found or an error
     **                           occurred blanks are returned to the caller.
     **
     **                  NOTE:    The resource name that is returned is
     **                           for the first port on the I/O adapter
     **                           in card position B of the first multi-
     **                           multifunction IOP on the bus.
     **
     **                           If both SDLC lines for the original ECS
     **                           modem and a PPP line for the iSeries Uni-
     **                           versal Connection for Electronic Support
     **                           and Service are configured for the adapter
     **                           the first resource name is returned.
     **
     **                           Run the command WRKHDWRSC TYPE(*CMN) and
     **                           specify option 5 to find out which lines
     **                           are configured for the specified resource.
