RZ(1) DG/UX R4.11 RZ(1)
NAME
rz - ZMODEM (Batch) file receive
SYNOPSIS
rz [- +1abDepqtuv]
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,
Unix, and other operating systems.
rz (Receive ZMODEM) receives files with the ZMODEM batch protocol.
rz on DG/UX does not support the YMODEM or XMODEM protocols.
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:
1 Use file descriptor 1 for ioctls and reads (Unix only). By
default, file descriptor 0 is used for ioctls and reads.
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.
D Output file data to /dev/null; for testing.
e Force sender to escape all control characters; normally XON,
XOFF, DLE, CR-@-CR, and Ctrl-X are escaped.
p (ZMODEM) 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.
Compile time options required for various operating systems are described in
the source file.
NOTES
The Unix "ulimit" parameter must be set high enough to permit large
file transfers.
The TTY input buffering on some systems may not allow long blocks or
streaming input at high speed. You should suspect this problem when
you can't send data to the Unix system at high speeds using ZMODEM.
If the system's tty line handling is really broken, the serial port
or the entire system may not survive the onslaught of long bursts of
high speed data.

ZMODEM CAPABILITIES
rz supports incoming ZMODEM binary (-b), ASCII (-a), protect (-p),
and append (-+) requests, and ZMODEM command execution.
FILES
rz.c, zmodem.h source files.
/tmp/rzlog stores debugging output generated with -vv option.
