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