    station.  Arguments:

    frame         Specifies the contents of the header of the frame
                  that caused the FRMR frame to be generated.

    reason

                  control      A received control field is undefined
                               or is not implemented.

                               incorrect length.

                  length       A received information field exceeds
                               the maximum length.

                  nr           A received control field contains an
                               invalid n(r).

                  ns           A received control field contains an

    This event is generated when an FRMR (frame reject) frame is
    received from the remote station.  Arguments:

    frame         Specifies the contents of the header of the
                  received FRMR frame.

    frame reject  Specifies why the frame was rejected. See possible
    reason        reasons described under the Frame Reject Reason
                  argument of the Frame Reject Generated event.

 o  link halted

 o  link running

    This event is generated when the status attribute protocol
    state is set to Running. This means that the protocol has been
    successfully initialized or reset.

 o  link setup failure

    This event is generated when llc2 protocol initialization has
    failed after the maximum number of retries.

 o  link state changed

    This event is generated when the status attribute state changes
    from On to Off, or from Off to On.
