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.
