    Problem Text
    The test is supposed to work as follows:
    SLAVE MASTER

    t_conrq() ----> T_CONNECT event
    t_listen()
    t_disrq() ----> T_DISCONNECT event
    t_accept() ==> TLOOK


    This test sequence works perfectly for transport providers different from
    ISO class 2.
    In case of ISO cl.2 the test sequence looks a bit different:
    SLAVE MASTER

    t_conrq() ----> T_CONNECT event
    t_listen()
    t_disrq()
    (NOT TRANSMITTED BUT
    STORED LOCALLY) t_accept() ==> T_OK

    For ISO cl.2 the t_disrq() won't be transmitted as long as the connection
    request is still "pending" (i.e. neither confirmed nor rejected) but is
    stored locally. As a consequence, the T_DISCONNECT event does not occur
    on master side causing the t_accept() call to complete successfully.
    Acc. to ISO 8073, a connection request leads to state WFCC; a
    subsequent disconnect request changes the state to WBCL without further
    action (see IS 8073, Appendix A, table 15 for details).
    We think this test is simply not applicable for an ISO cl.2 transport provider.

    Repeat of waiver for VST 4.1.4.
    Test Output
    /tset/XTI.os/cots/accept/T.accept 22 Unresolved
    Test Description:
    If the implementation supports a connection-oriented transport service:
    When a T_DISCONNECT event that requires immediate attention has
    occurred on fd, then t_accept() returns (int)-1, sets t_errno to
    TLOOK and the states of the endpoints fd and resfd are not changed.

    Test Information:
    NO EVENT occurred on ISO CLASS 2 endpoint instead of expected
    T_DISCONNECT event
