    Problem Text
    This test may fail on implementations that deviate from the standard
    by following historical practice.

    These tests are resolved by the following IEEE POSIX interpretation,
    which permits the behaviour exhibited by our system. The resolution
    below shows that this part of the standard has a defect (concerns
    have been referred to the sponsor).

    Interpretation Request:
    -----------------------

    From: andrew@novell.co.uk (Andrew Josey)

    For the attention of :

    Secretary, IEEE Standards Board

    This is a request for interpretation of IEEE Std POSIX 1003.2-92

    Topic: stty
    Sections: 4.59.4.6

    Section 4.59.4.6 states:

    9944 nl (-nl) Enable (disable) icrnl. In addition, -nl unsets
    9945 inlcr and igncr.

    In the case of nl, this specifies the exact opposite of historical SysV
    practice, from which the definition of stty is taken.

    SVID 3 states (minus output modes which aren't specified by POSIX):

    nl (-nl) Unset (set) icrnl. In addtion -nl unsets inlcr, igncr.

    This appears to be a straightforward editorial error. The standard should
    read:

    9944 nl (-nl) Disable (enable) icrnl. In addition, -nl disables
    9945 inlcr and igncr.

    Please could you clarify if the standard is in error?


    Interpretation response
    ------------------------


    The standard states the requirement for stty nl
    and conforming implementations must conform
    to this. However concerns have been raised about this which are
    being referred to the sponsor.
