Annotation of embedaddon/lrzsz/COMPATABILITY, revision 1.1.1.1

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.
