    Problem Text
    This test may fail on implementations that to not support
    split input/output baud rates.

    This interpretation request is for the following assertions:

    /tset/POSIX.cmd/stty/stty.ex 1 assertion 21
    /tset/POSIX.cmd/stty/stty.ex 1 assertion 23

    These tests fail on our implementation because we do not support
    split baud rates. The XPG4 V2 XSH spec on page 648 states the following:

    "... If the terminal device does not support split baud rates, the input
    baud rate stored in the termios structure will be 0."

    For tp21, check_stty is called, which contains the following code:

    if (tcgetattr(0, &tio) < 0) /* orignial termios struct */
    .
    .
    .
    .
    if (isdigit(argv[1][0])) /* get i_speed and o_speed operand */
    {
    /* input baud rate should be the same as output baud rate */
    ispeed = cfgetispeed(&tio);
    ospeed = cfgetospeed(&tio);
    if (ospeed == ispeed)
    /* Check if the baud stored in termios is the same as
    * stty <number> specified, if they are the same,
    * return 0; otherwise, return 1
    */
    exit(check_speed(ospeed, argv[1]));
    else
    {
    fprintf(stderr, "stty %s setting error\n", argv[1]);
    exit(2);
    }
    }

    Since we don't support split baud rates, the cfgetispeed() call will
    always set ispeed to zero. The comparision of ispeed and ospeed will
    always fail.

    For tp23 check_stty ispeed 0 is called and the following code is
    executed in check_stty:


    case 6:
    ispeed = cfgetispeed(&tio);
    if (strcmp(argv[2], "0") == 0)
    exit(ispeed == cfgetospeed(&tio) ? 0:1);
    else
    exit(check_speed(ispeed, argv[2]));

    ispeed on our implementation will always be 0, so ispeed == cfgetospeed(&tio)
    will always evaluate to 0, which causes exit(1) to be executed. This
    will cause tp23 to report a failure.

    Note, TSD4.248 was granted for VSX, on this problem.
