- NAME
- rz - XMODEM, YMODEM, ZMODEM (Batch) file receive
-
-
- SYNOPSIS
- rz [-2abuv] [-s<speed>] [-] (ZMODEM Batch)
- rz [-2abuv] [-s<speed>] [-] -Y (YMODEM Batch)
- rz [-2abcv] [-s<speed>] file (XMODEM)
-
- DESCRIPTION
- This program uses error correcting protocol to receive files
- over a serial port from a variety of programs running under Unix,
- PC-DOS, CP/M, and other operating systems.
-
- Rz (Receive ZMODEM) receives files with the ZMODEM batch protocol.
- If the sending program does not support ZMODEM, rz steps down to
- YMODEM protocol after 50 seconds. This delay can be eliminated by
- calling the program as rz -Y.
-
- When receiving with XMODEM or YMODEM, rz accepts either standard
- 128 byte sectors or 1024 byte sectors (YAM -k option). The user
- should determine when the longer block length actually improves
- throughput without causing problems.
-
- If extended file information (file length, etc.) is received,
- the file length controls the number of bytes written to
- the output dataset (YMODEM only), and the modify time and file
- mode (if non zero) are set accordingly.
-
- If no extended file information is received, slashes in the
- pathname are changed to underscore, and any trailing period in the
- pathname is eliminated. This conversion is useful for files received
- from CP/M systems.
-
- The second form of receives a single with XMODEM protocol. The
- user must supply the file name to both sending and receiving
- programs. rz -X file
-
- If rz is invoked with stdout and stderr to different datasets,
- Verbose is set to 2, causing frame by frame progress reports
- to stderr. This may be disabled with the q option.
-
- The meanings of the available options are:
-
- 2 Use COM2 instead of COM1 (MS-DOS only). By default,
- COM1 is used.
-
- a Convert files to Unix conventions by stripping carriage
- returns and all characters beginning with the first
- Control Z (CP/M end of file).
-
- b Binary (tell it like it is) file transfer override.
-
- c Request 16 bit CRC. XMODEM file transfers default to 8
- bit checksum. YMODEM and ZMODEM normally use 16 bit CRC.
-
- p Protect: skip file if destination file exists.
-
- q Quiet suppresses verbosity.
-
- t tim Change timeout to tim tenths of seconds.
-
- v Verbose causes a list of file names to be appended to
- /tmp/rzlog. More v's generate more output.

- BUGS
- Pathnames are restricted to 127 characters. In XMODEM single file
- mode, the pathname given on the command line is still processed as
- described above. The ASCII option's CR/LF to NL translation merely
- deletes CR's; undos(omen) performs a more intelligent translation.
-
- Non binary file processing consists of stripping all characters
- beginning with CPMEOF (^Z).
-
- FILES
- /tmp/rzlog stores debugging output generated with -vv option.
