    * PROBLEM DESCRIPTION: After PTF's for IO03985 were installed, *
    *                      the physical NTRI line would hang       *
    *                      causing INOP's at the adjacent nodes.   *

    * RECOMMENDATION: Apply appropriate PTF.                       *
    ****************************************************************
    An SCB clear with the MAC transmitter pending caused
    the L3 routine to be stored in the wrong PLUACB, however the
    correct PLUACB was posted, causing ECLLXMT to run instead of
    ECLMXMT.
    

Problem conclusion

  • The L3 routine will be stored in the correct PLUACB.  Also,
    the LLC transmitter had code added to delay transmitting if
    the MAC transmitter is pending for transmission.
