PCZ - A Public Domain implementation
of Zmodem, Xmodem, Xmodem-1K, Sealink,
Ymodem for the IBM PC family

PcConnect Zmodem by Drue Kennon and Gary Smith

PCZ is a public domain Zmodem implementation that will allow
users of communication software that does not implement internal
Zmodem to access it through an external program. It is a
fully-featured version of Zmodem, but does not have the
professional and commercial polish of a program like Omen
Tech's DSZ. However we do believe that it will be suitable
for the average BBS'r.

PCZ also provides support for the basic Xmodem variants:
Xmodem, Xmodem-1K, Sealink, and Ymodem Batch.

Command line:
PCZ [port (1-4)] [speed (300-9600)] [sz] (r)

PCZ [port (1-4)] [speed (300-9600)] [rz]

The entering of the words << port & speed >> are optional.

Default port = 1; Default speed = 2400;

To receive a file using Zmodem simply enter :

|-- PCZ rz - Using com port one.
batch | PCZ 2 rz - Using com port two.
modes | PCZ 3 2400 rz - Using com port three at 2400 baud.
|-- PCZ 4 1200 rz - Using com port four at 1200 baud.

PCZ rz INFILE.ARC - Receive one file and name it INFILE.ARC

To send a file using Zmodem simply enter :

PCZ sz OUTFILE.ARC - Using com port one.
PCZ 2 sz OUTFILE.ARC - Using com port two.
PCZ 3 2400 sz OUTFILE.ARC - Using com port three at 2400 baud.
PCZ 4 1200 sz OUTFILE.ARC - Using com port four at 1200 baud.
PCZ sz r OUTFILE.ARC - Send file and resume transfer.

To send a batch of files via Zmodem :

Create a text file with one complete file spec per line,
with a maximum of 25 files allowed.
Have no blank lines in the file and place the "@" symbol
as the first character of the dos file name. Pass it
to PCZ on the command line as follows:

PCZ 1 2400 sz @OUTFILE.TXT - Using port 1 at 2400 baud.

To receive files using any of the Xmodem variants, the format is :

PCZ rs filename - Sealink recieve
PCZ rx filename - Xmodem receive
PCZ r1 filename - Xmodem-1K receive
PCZ ry filename - Ymodem receive
PCZ ry - Ymodem Batch receive

To send files using any of the Xmodem variants, the format is :

PCZ ss filename - Sealink
PCZ sx filename - Xmodem
PCZ s1 filename - Xmodem-1K
PCZ sy filename - Ymodem

If you want PCZ to keep a file transfer log then the following line must be
added to your autoexec.bat file or typed in on the command line.

set pczlog=d:\mycommdir;

where d is the drive & mycommdir is where you want the logfile to be placed.

Note: the bytes and cps rate reflect the actual number of bytes sent
to or received. It does not necessarily reflect any specific "BLOCKSIZE".
This will let you see actually how PCZ is progressing in the transmission
of data. In the best case "Full Streaming Zmodem", you will see the time
for actual file data; worse case time will reflect the transmission of
data headers and block acks. It is different, but I hope everyone can
appreciate a more accurate account of what is happening inside the powerful
zmodem protocol.


V1.01.88 - Intial release, no known bugs. Please report
any problems to Drue Kennon or Gary Smith.

V2.01.89 - Extended version that contains Xmodem, Xmodem-1K,
Sealink, and Ymodem Batch in addition to Zmodem.
Also does provide full file sharing for use in
networking enviroments.

Fixed several reported bugs. Enabled hardware flow
control for use with MNP type modems. Enhanced port
speeds up to 19.2k, and tightened some code for
more efficient operation. Properly set errorlevel 1
in event of transfer failure.
