.RB [ \- ][ v ] rzCOMMAND
|
|
||||||
.SH DESCRIPTION
|
|
||||||
This program uses error correcting protocol to receive
|
|
||||||
files over a serial port from a variety of programs running under
|
|
||||||
PC-DOS, CP/M,
|
|
||||||
.SM Unix,
|
|
||||||
and other operating systems.
|
|
||||||
|
|
||||||
The first form of
|
|
||||||
.B rz
|
|
||||||
(Receive Batch)
|
|
||||||
receives files with ZMODEM batch protocol.
|
|
||||||
If the sending program does not support ZMODEM,
|
|
||||||
.B rz
|
|
||||||
steps down to YMODEM protocol
|
|
||||||
after 50 seconds.
|
|
||||||
This delay can be eliminated by calling the program as
|
|
||||||
.I rb .
|
|
||||||
|
|
||||||
.B Rb
|
|
||||||
accepts either standard 128 byte sectors or
|
|
||||||
1024 byte sectors
|
|
||||||
(YAM
|
|
||||||
.B -k
|
|
||||||
option).
|
|
||||||
The user should determine experimentally
|
|
||||||
the conditions under which use of 1k blocks
|
|
||||||
actually improves throughput without causing
|
|
||||||
problems.
|
|
||||||
|
|
||||||
Normally, the file contents are converted to
|
|
||||||
.SM Unix
|
|
||||||
conventions by stripping carriage returns and all characters
|
|
||||||
beginning with Control Z (CP/M end of file).
|
|
||||||
If the raw pathname ends in
|
|
||||||
".A",
|
|
||||||
".ARC",
|
|
||||||
".CCC",
|
|
||||||
".CL",
|
|
||||||
".CMD",
|
|
||||||
".COM",
|
|
||||||
".CRL",
|
|
||||||
".DAT",
|
|
||||||
".DIR",
|
|
||||||
".EXE",
|
|
||||||
".O",
|
|
||||||
".OBJ",
|
|
||||||
".OVL",
|
|
||||||
".PAG",
|
|
||||||
".REL",
|
|
||||||
".SAV",
|
|
||||||
".SUB",
|
|
||||||
".SWP",
|
|
||||||
".SYS",
|
|
||||||
".TAR",
|
|
||||||
".UTL",
|
|
||||||
".a",
|
|
||||||
".o",
|
|
||||||
".tar",
|
|
||||||
or if the first packet contains
|
|
||||||
data that suggest a binary file
|
|
||||||
(parity bits or characters in the range 000 to 006 before the first ^Z),
|
|
||||||
or if the file mode is transmitted and the 0100000
|
|
||||||
bit is set, that file will be received in binary mode anyway.
|
|
||||||
Otherwise,
|
|
||||||
if the raw pathname ends in .MSG, or .TXT, an existing file will
|
|
||||||
be appended to rather than replaced.
|
|
||||||
|
|
||||||
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
|
|
||||||
(iff 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.
|
|
||||||
Normally, each file name is converted to lower case
|
|
||||||
unless it contains one or more lower case letters.
|
|
||||||
|
|
||||||
|
|
||||||
The second form of
|
|
||||||
.B rz
|
|
||||||
receives a single
|
|
||||||
.I file
|
|
||||||
with XMODEM protocol.
|
|
||||||
The user must supply the file name to both sending and receiving programs.
|
|
||||||
|
|
||||||
|
|
||||||
The third form of
|
|
||||||
.B rz
|
|
||||||
is invoked as
|
|
||||||
.B rzCOMMAND
|
|
||||||
(with an optional leading \- as generated by login(1)).
|
|
||||||
For each received file,
|
|
||||||
rz will pipe the file to ``COMMAND filename''
|
|
||||||
where filename is the name of the transmitted file
|
|
||||||
with the file contents as standard input.
|
|
||||||
|
|
||||||
Each file transfer is acknowledged when COMMAND exits with 0 status.
|
|
||||||
A non zero exit status terminates transfers.
|
|
||||||
|
|
||||||
A typical use for this form is
|
|
||||||
.I rzrmail
|
|
||||||
which calls rmail(1)
|
|
||||||
to post mail to the user specified by the transmitted file name.
|
|
||||||
For example, sending the file "caf" from a PC-DOS system to
|
|
||||||
.I rzrmail
|
|
||||||
on a
|
|
||||||
.SM Unix
|
|
||||||
system
|
|
||||||
would result in the contents of the DOS file "caf" being mailed to user "caf".
|
|
||||||
|
|
||||||
On some
|
|
||||||
.SM Unix
|
|
||||||
systems, the login directory must contain a link to
|
|
||||||
COMMAND as login sets SHELL=rsh which disallows absolute
|
|
||||||
pathnames.
|
|
||||||
If invoked with a leading ``v'',
|
|
||||||
.B rz
|
|
||||||
will report progress to LOGFILE.
|
|
||||||
The following entry works for
|
|
||||||
.SM Unix
|
|
||||||
3.0:
|
|
||||||
.ce
|
|
||||||
rzrmail::5:1::/bin:/usr/local/rzrmail
|
|
||||||
If the SHELL environment variable includes
|
|
||||||
.I "rsh"
|
|
||||||
or
|
|
||||||
.I "rksh"
|
|
||||||
(restricted shell),
|
|
||||||
rz will not accept absolute pathnames
|
|
||||||
or references to a parent directory,
|
|
||||||
will not modify an existing file, and
|
|
||||||
removes any files received in error.
|
|
||||||
|
|
||||||
If
|
|
||||||
.B 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
|
|
||||||
.B q
|
|
||||||
option.
|
|
||||||
|
|
||||||
.PP
|
|
||||||
The meanings of the available options are:
|
|
||||||
.PP
|
|
||||||
.PD 0
|
|
||||||
.TP
|
|
||||||
.B 1
|
|
||||||
Use file descriptor 1 for ioctls and reads (Unix only).
|
|
||||||
By default, file descriptor 0 is used.
|
|
||||||
This option allows
|
|
||||||
.B rz
|
|
||||||
to be used with the
|
|
||||||
.I cu
|
|
||||||
~$
|
|
||||||
command.
|
|
||||||
.TP
|
|
||||||
.B b
|
|
||||||
Transfer all files in binary
|
|
||||||
(tell it like it is)
|
|
||||||
mode.
|
|
||||||
This option disables file append.
|
|
||||||
.TP
|
|
||||||
.B c
|
|
||||||
Request 16 bit CRC
|
|
||||||
(XMODEM file transfers default to 8 bit checksum).
|
|
||||||
Batch transfers use 16 bit CRC.
|
|
||||||
.TP
|
|
||||||
.B D
|
|
||||||
Output file data to /dev/null; for testing.
|
|
||||||
.TP
|
|
||||||
.B q
|
|
||||||
Quiet suppresses verbosity.
|
|
||||||
.TP
|
|
||||||
.B v
|
|
||||||
Verbose
|
|
||||||
causes a list of file
|
|
||||||
names to be appended to
|
|
||||||
/tmp/rzlog .
|
|
||||||
More v's generate more output.
|
|
||||||
.TP
|
|
||||||
.B u
|
|
||||||
Retain upper case letters in file names.

.SH 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 CR/LF to NL translation merely deletes CR\'s;
|
|
||||||
undos(omen) performs a more intelligent translation.
|
|
||||||
.SH "VMS VERSION"
|
|
||||||
Some of the #includes with file names enclosed with angle brackets <>
|
|
||||||
may need to have the angle brackets changed to "", or vice versa.
|
|
||||||
|
|
||||||
The VMS version does not set binary mode according to the incoming
|
|
||||||
file type.
|
|
||||||
Non binary file processing consists of stripping all characters beginning
|
|
||||||
with CPMEOF (^Z).
|
|
||||||
|
|
||||||
The VMS version does not set the file time.
|
|
||||||
|
|
||||||
At high speeds,
|
|
||||||
VMS sometimes loses incoming characters, resulting in retries
|
|
||||||
and degradation of throughput.
|
|
||||||
|
|
||||||
The mysterious
|
|
||||||
VMS C Standard I/O Package and RMS may interact to modify
|
|
||||||
file contents unexpectedly.
|
|
||||||
|
|
||||||
The VMS version does not support invocation as
|
|
||||||
.B rzCOMMAND .
|
|
||||||
ZMODEM has not yet been implemented on the VMS version.
|
|
||||||
.SH "ZMODEM CAPABILITIES"
|
|
||||||
.B Rz
|
|
||||||
supports incoming ZMODEM binary (-b), ASCII (-a), and append (-+)
|
|
||||||
requests, and ZMODEM command execution.
|
|
||||||
.SH FILES
|
|
||||||
rz.c, rbsb.c, zm.c, zmodem.h source files.

.SH DESCRIPTION
|
|
||||||
.B Sz
|
|
||||||
uses the ZMODEM, YMODEM or XMODEM error correcting protocol to send
|
|
||||||
one or more files over a serial port to a variety of programs running under
|
|
||||||
PC-DOS, CP/M, Unix, VMS, and other operating systems.
|
|
||||||
|
|
||||||
|
|
||||||
The first form of
|
|
||||||
.B sz
|
|
||||||
sends one or more files with ZMODEM or YMODEM batch protocol.
|
|
||||||
Normally, only the file name part of the pathname is transmitted.
|
|
||||||
On
|
|
||||||
.SM Unix
|
|
||||||
systems, additional information about the file is transmitted.
|
|
||||||
If the receiving program uses this information,
|
|
||||||
the transmitted file length controls the exact number of bytes written to
|
|
||||||
the output dataset,
|
|
||||||
and the modify time and file mode
|
|
||||||
are set accordingly.
|
|
||||||
|
|
||||||
Output from another program may be piped to
|
|
||||||
.B sz
|
|
||||||
for transmission by specifying the
|
|
||||||
.B -1
|
|
||||||
option and denoting standard input by "-":
|
|
||||||
.ce
|
|
||||||
ps -ef | sz -
|
|
||||||
The program output is transmitted with the filename sPID.sz
|
|
||||||
where PID is the process ID of the
|
|
||||||
.B sz
|
|
||||||
program.
|
|
||||||
If the environment variable
|
|
||||||
.B ONAME
|
|
||||||
is set, that is used instead.
|
|
||||||
In this case, the Unix command:
|
|
||||||
.ce
|
|
||||||
ONAME=con ps -ef|sz -ay -
|
|
||||||
will send a "file" to the PC-DOS console display.
|
|
||||||
The
|
|
||||||
.B -y
|
|
||||||
bypasses the receiver\'s checking of the output filename.
|
|
||||||
The
|
|
||||||
.B -a
|
|
||||||
causes the receiver to convert Unix newlines to PC-DOS carriage returns
|
|
||||||
and linefeeds.
|
|
||||||
|
|
||||||
Unix
|
|
||||||
.B sz
|
|
||||||
supports
|
|
||||||
.B YMODEM-g
|
|
||||||
with "cbreak" tty mode, XON/XOFF flow control,

.B YMODEM-g
|
|
||||||
(Professional-YAM
|
|
||||||
.B g
|
|
||||||
option)
|
|
||||||
increases throughput over error free channels
|
|
||||||
(direct connection, X.PC, etc.)
|
|
||||||
by not acknowledging each transmitted sector.
|
|
||||||
|
|
||||||
|
|
||||||
The second form of
|
|
||||||
.B sz
|
|
||||||
uses the
|
|
||||||
.B -X
|
|
||||||
flag to send a single
|
|
||||||
.I file
|
|
||||||
with
|
|
||||||
.B XMODEM
|
|
||||||
protocol.
|
|
||||||
The user must supply the file name to both sending and receiving programs.
|
|
||||||
|
|
||||||
Iff
|
|
||||||
.B sz
|
|
||||||
is invoked with $SHELL set and iff that variable contains the
|
|
||||||
string
|
|
||||||
.I "rsh"
|
|
||||||
or
|
|
||||||
.I "rksh"
|
|
||||||
(restricted shell), sz operates in restricted mode.
|
|
||||||
Restricted mode restricts pathnames to the current directory and
|
|
||||||
PUBDIR (usually /usr/spool/uucppublic) and/or subdirectories
|
|
||||||
thereof.
|
|
||||||
|
|
||||||
|
|
||||||
The third form sends a single COMMAND to the receiver for execution.
|
|
||||||
.B Sz
|
|
||||||
exits with the COMMAND return value.
|
|
||||||
If COMMAND includes spaces or characters special to the shell,
|
|
||||||
it must be quoted.
|
|
||||||
|
|
||||||
The fourth form sends a single COMMAND to the receiver for execution.
|
|
||||||
.B Sz
|
|
||||||
exits as soon as the receiver has received the command, before it is executed.
|
|
||||||
|
|
||||||
|
|
||||||
If sz is invoked with stdout and stderr to different datasets,
|
|
||||||
Verbose is set to 2, causing frame by frame progress reports
|
|
||||||
to stderr.
|
|
||||||
This may be disabled with the
|
|
||||||
.B q
|
|
||||||
option.
|
|
||||||
.PP
|
|
||||||
The meanings of the available options are:
|
|
||||||
.PP
|
|
||||||
.PD 0
|
|
||||||
.TP
|
|
||||||
.B +
|
|
||||||
Force the receiver to append transmitted data to an existing file
|
|
||||||
(ZMODEM only).
|
|
||||||
.TP
|
|
||||||
.B 1
|
|
||||||
Use file descriptor 1 for ioctls and reads (Unix only).
|
|
||||||
By default, file descriptor 0 is used.
|
|
||||||
This option allows
|
|
||||||
.B sz
|
|
||||||
to be used with the
|
|
||||||
.I cu
|
|
||||||
~$
|
|
||||||
command.
|
|
||||||
.TP
|
|
||||||
.B a
|
|
||||||
Convert NL characters in the transmitted file to CR/LF.
|
|
||||||
This is done by the sender for XMODEM and YMODEM, by the receiver
|
|
||||||
for ZMODEM.
|
|
||||||
.TP
|
|
||||||
.B "c COMMAND"
|
|
||||||
Send COMMAND to the receiver for execution, return with COMMAND\'s exit status.
|
|
||||||
.TP
|
|
||||||
.B "C N"
|
|
||||||
Make N attempts at ten second intervals
|
|
||||||
to read COMMAND\'s exit status before exiting.
|
|
||||||
.TP
|
|
||||||
.B d
|
|
||||||
Change all instances of "." to "/" in the transmitted pathname.
|
|
||||||
Thus, C.omenB0000 (which is unacceptable to MSDOS or CP/M)
|
|
||||||
is transmitted as C/omenB0000.
|
|
||||||
If the resultant filename has more than 8 characters in the stem,
|
|
||||||
a "." in inserted to allow a total of eleven.
|
|
||||||
.TP
|
|
||||||
.B f
|
|
||||||
Send Full pathname.
|
|
||||||
Normally directory prefixes are stripped from the transmitted
|
|
||||||
filename.
|
|
||||||
.TP
|
|
||||||
.B "i COMMAND"
|
|
||||||
Send COMMAND to the receiver for execution, return Immediately.
|
|
||||||
.TP
|
|
||||||
.B k
|
|
||||||
Send files using YMODEM 1024 byte blocks
|
|
||||||
rather than the default 128 byte blocks.
|
|
||||||
1024 byte packets speed file transfers at high bit rates.
|
|
||||||
(ZMODEM streams the data for the best possible throughput.)
|
|
||||||
.TP
|
|
||||||
.B n
|
|
||||||
Instruct ZMODEM receiver to skip files if the length and modification times
|
|
||||||
of the source file and the file on the destination system are equal.
|
|
||||||
.TP
|
|
||||||
.B N
|
|
||||||
Instruct ZMODEM receiver to skip files if the length and CRC\'s
|
|
||||||
of the source file and the file on the destination system are equal.
|
|
||||||
.TP
|
|
||||||
.B q
|
|
||||||
Quiet suppresses verbosity.
|
|
||||||
.TP
|
|
||||||
.B r
|
|
||||||
Resume interrupted file transfer.
|
|
||||||
If the source file is longer than the destination file,
|
|
||||||
the transfer commences at the offset in the source file that equals
|
|
||||||
the length of the destination file.
|
|
||||||
.TP
|
|
||||||
.B u
|
|
||||||
Unlink the file after successful transmission.
|
|
||||||
.TP
|
|
||||||
.B v
|
|
||||||
Verbose
|
|
||||||
causes a list of file
|

/tmp/szlog .
|
|

.TP
|

with conversion
|

.RB ( -a )
|

to PC-DOS end of line conventions.

This Makefile fragment uses
|
|
||||||
.B sz
|
|
||||||
to issue commands to Professional-YAM to change current disk and directory.
|
|
||||||
Next,
|
|
||||||
.B sz
|
|
||||||
transfers the
|
|
||||||
.I .me
|
|
||||||
files from the $YD directory, commanding the receiver to overwrite the old files
|
|
||||||
and to convert from Unix end of line conventions to PC-DOS conventions.
|
|
||||||
The third line transfers some
|
|
||||||
.I .exe
|
|
||||||
files.
|
|
||||||
The fourth and fifth lines command Pro-YAM to
|
|
||||||
change directory and execute a PC-DOS batch file
|
|
||||||
.I insms .
|
|
||||||
Since the batch file takes considerable time, the
|
|
||||||
.B "-i"
|
|
||||||
form is used to allow
|
|
||||||
.B sz
|
|
||||||
to exit immediately.

|
|

.SH "VMS VERSION"
|
|
||||||
The VMS version does not transmit the file date.
|
|
||||||
The VMS version calculates the file length by reading the file
|
|
||||||
and counting the bytes.
|
|
||||||
|
|
||||||
The VMS version does not support YMODEM-g or ZMODEM.
|
|
||||||
|
|
||||||
When VMS is lightly loaded, the response time may be too quick for MODEM7
|
|
||||||
unless the MODEM7
|
|
||||||
.B "q"
|
|
||||||
modifier is used.
|
|
||||||
|
|
||||||
The VMS C standard i/o package and RMS sometimes interact to modify
|
|
||||||
file contents unexpectedly.

.SH "TESTING FEATURE"
|
|
||||||
The command "sz -T file"
|
|
||||||
exercises the
|
|
||||||
.B Attn
|
|
||||||
sequence error recovery by commanding
|
|
||||||
errors with unterminated packets.
|
|
||||||
The receiving program should complain five times about
|
|
||||||
binary data packets being too long.
|
|
||||||
Each time
|
|
||||||
.B sz
|
|
||||||
is interrupted,
|
|
||||||
it should send a ZDATA header followed by another defective packet.
|
|
||||||
If the receiver does not detect five long data packets,
|
|
||||||
the
|
|
||||||
.B Attn
|
|
||||||
sequence is not interrupting the sender, and the
|
|
||||||
.B Myattn
|
|
||||||
string in
|
|
||||||
.B sz.c
|
|
||||||
must be modified.
|
|
||||||
|
|
||||||
After 5 packets,
|
|
||||||
.B sz
|
|
||||||
stops the "transfer" and
|
|
||||||
prints the total number of characters "sent" (Tcount).
|
|
||||||
The difference between Tcount and 5120 represents the number of characters
|
|
||||||
stored in various buffers when the Attn sequence is generated.
|
|
||||||
.SH BUGS
|
|
||||||
XMODEM transfers add up to 127 spurious bytes per file.
|
|
||||||
|
|
||||||
Circular buffering and a ZMODEM sliding window should be used
|
|
||||||
when input is from pipes instead of acknowledging frames each 1024 bytes.
|
|
||||||
.B Sz
|
|
||||||
should check for the presence of at least one accessible file before
|
|
||||||
getting hot and bothered.
|
|
||||||
The test mode leaves a zero length file on the receiving system.

||||||
