o  buffer too small

    Generated each time a message is received whose data field is
    larger than the buffers available on the local station.

    Arguments:

    buffer      Specifies the size of the receive buffer at the local
    size        station.

    count       Specifies the size of the received data message as
                specified in the message header.

 o  locally initiated state change

    Generated each time the state of the local station changes as a
    result of action on the local node.

    Arguments:

    new state   New value of the logical station's protocol state
                attribute.

    old state   Previous value of the logical station's protocol
                state attribute.

 o  receive error threshold reached

    Generated each time the number of consecutive receive-related
    errors reaches the receive error threshold limit of 7.

 o  remotely initiated state change

    Generated each time the state of the link changes as a result of
    action on the remote node.

    Arguments:

    new state   New value of the logical station's protocol state
                attribute.

    old state   Previous value of the logical station's protocol
                state attribute.

 o  selection error threshold reached

    This event is generated each time the number of consecutive
    selection-related errors reaches the selection error threshold
    limit of 7. This event is supported only when the protocol
    characteristic of the owning ddcmp link entity is set to control,
    or when the link is half-duplex point-to-point.

 o  send error threshold reached

    This event is generated each time the number of consecutive
    transmit related errors reaches the transmit error threshold
    limit of 7.

 o  strt received while in maintenance

    This event is generated each time a strt message is received
    while the value of the status attribute protocol state of the
    local station is set to maintenance.
