What is sdlcCuReceivedRNR?

This read-only counter tallies RNR (Receiver Not Ready) frames received from this control unit (TIU SAP) or from the host (HIU SAP). A rising count tells an admin the remote peer is repeatedly signaling it can't accept more frames, a possible sign of buffer or processing overload there.
