    Problem Text
    XPG4 requires a SIGHUP signal to be sent to the controlling process of the
    controlling terminal when the controlling terminal detects a modem disconnect.
    However, this test expects a SIGHUP signal to be sent when the controlling
    terminal generates a modem disconnect. The loopback terminal actually detects
    a modem disconnect, but since the loopback terminal is not the controlling
    terminal, no SIGHUP signal is sent.

    This has been a controversial test in the past. X/Open interpretation
    VWG/012/063092 describes this problem and states that an interpretation
    request has been forwarded to IEEE. It also suggests that a temporary
    interpretation will be granted until an IEEE interpretation becomes
    available.
    Test Output
    /tset/POSIX.os/devclass/cfsetospee/T.cfsetospee 3 Failed

    Test Description:
    If general terminal interface supported:
    If modem control is supported, when cfsetospeed(termios_p, B0) and
    tcsetattr(fildes, optional_actions, termios_p) are successfully
    called, a modem disconnect shall occur.
    Posix Ref: Component TCSETATTR Assertion 7.2.1.2-08(C)

    Test Strategy:
    CREATE [child process|process pair]
    Parent: SET signal action for SIGHUP to signal catching function.
    WRITE data to loop back file using write()
    SLEEP for WAITTIME
    Child: READ from terminal file using read()
    SET signal action for SIGHUP to signal catching function.
    SET output baud rate B0 using cfsetospeed()
    SET terminal information using tcsetattr()
    Parent: SLEEP interrupted by signal
    VERIFY signal SIGHUP was caught

    Test Information:
    SIGHUP not received by controlling process
