Annotation of embedaddon/lrzsz/COMPATABILITY, revision 1.1

1.1     ! misho       1: ZModem standard:
        !             2:     lrzsz is compatible with standard zmodem as long as you don't use
        !             3:     certain options:
        !             4:     -8 is incompatible with the standard, but should work with most
        !             5:        DOS/Atari/Amiga ZModems. It's a common extension, but a dangerous
        !             6:        one. Do not use it unless you know that the receiver can handle it.
        !             7:     -S is incompatible with certain ZModems which use the TIMESYNC bit
        !             8:        for other purposes (timesync is a protocol extension by Peter
        !             9:        Mandrella, read timesync.doc for more information). The default
        !            10:        is to disable timesync, you must use the `S' option to enable it.
        !            11: 
        !            12: 
        !            13: Calling conventions:
        !            14:     lrzsz is not fully compatible with older UNIX ZModems:
        !            15:     - PUBDIR (/var/spool/uucppublic) is normally disabled. If you like
        !            16:       public writable directories please use:
        !            17:         configure --enable-pubdir=/var/spool/uucppublic
        !            18:     - lrz defaults to restricted mode, in which the sender must not upload
        !            19:       any files outside the working directory or PUBDIR (if pubdir is
        !            20:       enabled). With the old version you had to set SHELL=rsh.
        !            21:       For more information read the SECURITY paragraph in lrz.1.
        !            22:     - lrz: remote command execution is disabled. To enable it use -C (but
        !            23:       be careful - the sender might delete all your files).
        !            24:     - lrz: does not set executable bits for any files it received under
        !            25:       a restricted shell.
