    Problem Text
    The open() is for the pseudo-terminal lookback slave is failing with
    errno=EPERM because the default HUPCL setting for our tty's is ON.
    POSIX.1, section 7.1.2.4, lines 412 through 414 say "If HUPCL is set,
    the modem control lines for the port shall be lowered when the last
    process with the port open closes the port or the process terminates.
    The modem connection shall be broken." We believe it is appropriate
    for open() to fail in this situation.

    Line 426 of section 7.1.2.4 also states "The initial hardware control
    value after {open()} is implementation defined." The VSX4 suite should
    not expect that HUPCL is off for a tty before it is closed and
    re-opened.
    Test Output
    /tset/POSIX.os/devclass/i_close/T.i_close 2 Unresolved

    Test Description:
    If general terminal interface supported:
    The last process to close a terminal device file shall cause any
    data in the input queue to be discarded.
    Posix Ref: Component Terminal Interface Assertion 7.1.1.11-71(D)
