ZCOPY.COM VERSION 1.2 -- supersedes version 1.0
ORIGINALLY DESCRIBED IN PC MAGAZINE, FEB 28, 1989 VOL 8 NUMBER 4 PAGE 251
PURPOSE: Transfers files at high speed via a serial link
between machines that do not share a common disk format.
Null modem cable required.
FORMAT: ZCOPY source [target] [/w][/n][/u][/o][/a][/p][/d]
REMARKS: The two machines must be IBM-compatible and must be
connected by a standard null-modem cable. Zcopy is executed
with appropriate parameters, on both machines; a 30-second
default) connect time is provided.
On the sending machine both a source (filename plus any
needed drive and path) and a target (COM1 or COM 2) must be
specified. ZCOPY supports the * and ? DOS filename
wildcards," but it does not permit renaming files during
transfer. On the receiving machine the source is COM1 or
COM2 and the target, if specified, must be a directory path.
Any needed subdirectories must be created on the receiving
machine before using ZCOPY.)
The optional /w and /n switches operate before connection is
established, and so are entered on the ZCOPY command line of
each machine. The /w parameter prolongs the connection
timeout indefinitely; it can be canceled with Ctrl-Break.
The /n parameter sets the highest bit-per-second rate at
which ZCOPY will attempt to transfer data. If used it must be
the same on both machines. The default is /1 (115 kilobits
per second). Other acceptable values are /2 through /6
kbps, 38.4 kbps, 19.2 kbps, 9600 kbps, and 4800 kbps,
respectively). If ZCOPY cannot maintain error-free transfer
at a given transfer rate, it automatically steps down to the
next lower speed.
The other optional parameters may be entered on either
machine's ZCOPY command line. The /u (Update) switch permits
overwriting same-named files on the receiving machine without
operator confirmation if the source file is more recent. The
o (Overwrite) switch suppresses the confirmation prompt for
all files. By default, when ZCOPY receives a disk-full
signal, before aborting it tries to find a smaller selected
source file that will fit on the receiving disk. The /a
Abort on Full) aborts at the first disk-full indication.
The /p (Pause) switch creates a pause before the transfer
operation begins after the connection between machines has
been made, permitting changing a disk. The /d option changes
the date of a received file to that of the receiving machine.
