    Problem Text

    POSIX 1003.1-1990 on page 145 line 681 and XPG4 System Interfaces and
    Headers, Issue 4 page 459 under the description heading for tcsendbreak
    states that if "duration is not zero, it shall send zero-valued bits for
    an implementation-defined period of time." Our implementation-defined
    period of time is zero, and therefore no breaks are sent. We believe the
    test suite is in error.


    Test Output
    ************************************************************************
    /tset/POSIX.os/devclass/tcsendbrea/T.tcsendbrea 3 Failed

    Test Description:
    If general terminal interface supported:
    tcsendbreak(fildes, duration) when duration is negative causes
    transmission of a continuous stream of zero-valued bits for an
    implementation-defined period of time, and shall return zero.
    Posix Ref: Component TCSENDBREAK Assertion 7.2.2.2-05(D)

    Test Strategy:
    OPEN and initialise terminal file and loop back file
    CREATE process pair
    CHILD process:
    CREATE process session using setsid()
    OPEN loop back file as controlling terminal for new session
    SET signal action for SIGINT to be caught
    SLEEP for WAITTIME/2 to allow break to generate SIGINT signal
    PARENT process:
    SLEEP to allow child process to initialise
    SET time out for WAITTIME/2
    SEND a break using tcsendbreak(tty_fildes, -1)
    VERIFY that SIGINT signal was received by process controlled by loop
    back file
    VERIFY that tcsendbreak() returned zero.

    Test Information:
    SIGINT not received
