    Problem Text
    A MSF is requested for IUTs which do not properly parse the command
    line keystroke sequence, "^V^C". The IUT improperly interprets this
    as an interrupt.

    The test fails because the sequence "^V^C" is prematurely terminating
    the testcase in question.

    The comparison between results and expected output fails.

    As far as I have been able to see or test, historically, the Korn shell
    did not accept literal insertion of the INTR character. Our implementation
    has this fault. Hand typing all the other sequences of special characters
    does permit insertion of the corresponding special characters, i.e.,

    Typing "abc^V\ndef" produces "abc^Jdef" - Newline
    Typing "abc^V^Hdef" produces "abc^Hdef" - Erase
    Typing "abc^V^Udef" produces "abc^Udef" - Kill
    Typing "abc^V^Vdef" produces "abc^Vdef" - Control-V
    Typing "abc^V^Wdef" produces "abc^Wdef" - Control-W
    Typing "abc^V^Ddef" produces "abc^Ddef" - EOF
    Typing "abc^V^[def" produces "abc^[def" - ESC

    We believe that this system fault is a waiver candidate because a user is
    able to redefine the intr control character to a different value before
    entering the "^V^C" sequence. Also, we believe that application usage of
    this functionality is not widespread.

    A defect report has been opened and a fix will be available very rapidly.
    Unfortunately, this will most likely not be available in time to submit
    the branding application before 20th April. This would be the only MSF
    interpretation required by our branding application.

    Review Response
    We believe this issue will have no impact on applications. Our
    experience leads us to think it is very unlikely to affect
    interactive users either.

    A temporary waiver for a minor system fault is recommended.

    Review Conclusion
    A Temporary Waiver is granted.
