Following are the instructions that I used for setting up Zmodem. Everything
is correct except that the latest version is now DSZ0811.

INSTALLING AND USING ZMODEM FILE TRANSFER PROTOCOL
May 24, 1987


This file contains complete step-by-step instructions for setting your
system up for Zmodem, and for using Zmodem to upload or download files.
The instructions assume you are using Procomm as your terminal communi-
cations program; if you are using another terminal package, substitute
for the Procomm commands the appropriate commands for your particular
package.

If you set your system up per these instructions, you will need to enter
only "RZ" to download Zmodem or "SZ filespec" to upload Zmodem.


FILES NEEDED
============
DSZ.EXE The Zmodem driver. Check Dir1 for latest version. Version
currently posted on SPACE contained in DSZ0512.ARC.

CED.COM The CED program. Shareware version is posted on SPACE in
Dir10 as CED10D.ARC. (Note: You may also use the commercial
version of CED which is known as PCED.)

CED.CFG Text file created by you (see below) with CED synonymns.

PROCOMM.EXE The main communications program you are using. Substitute
your's if it is not Procomm.


SETTING UP YOUR SYSTEM FOR ZMODEM
=================================
The setup described here assumes that you locate the above files in the
the following directories; if you use different directories, change the
path specs accordingly:

PROCOMM.EXE is in directory C:\COMM
DSZ.EXE is in directory C:\COMM
CED.COM is in directory C:\DOS
CED.CFG is in directory C:\

1. Create a CED.CFG file, or add the following statements to your
existing file, to define CED synonymns for RZ and SZ:

syn RZ c:\comm\dsz pa5000 rz -y^EXIT
syn SZ c:\comm\dsz z pL1024 sz %1 %2^EXIT

2. Add the following statements to your AUTOEXEC.BAT file:

PATH c:\dos;c:\comm
CED -B128,128,128,128,128,128 -Fc:\ced.cfg
SET DSZPORT=2 (ONLY if your modem is on COM2)
SET PROCOMM=c:\comm\ (ONLY if you are using Procomm)

The PATH statement puts DSZ.EXE and CED.COM on your DOS path. If
you already have a PATH statement, add the directories containing the
two needed files to your PATH.

The CED statement sets up the necessary CED buffers and tells CED
where the CED.CFG file is located and to load it. If you already
have a CED.CFG file, you may need to increase the buffer size to
provide enough space for the new RZ and SZ synonymns.

The SET DSZPORT statement tells DSZ to use COM2. Include this
statement ONLY if your modem is connected to COM2. If your modem
is on COM1, a SET DSZPORT statement is not required (or you may
optionally set it to "1").

If you are using Procomm, the SET PROCOMM statement enables Procomm
to find its .PRM, .DIR, .XLT and .KEY files. The statement assumes
they are on C:\COMM. If they are in some other directory, change
the statement accordingly. Note: The final backslash ("\") in the
SET statement is mandatory for Procomm. If you are using a program
other than Procomm, consult your manual for environment variables
and proper syntax.


UPLOADING FILES WITH ZMODEM
============================
To upload (send) files to the host (BBS) system using Zmodem:

1. Select Zmodem protocol on the host system

2. If prompted by the host system, enter the name of the file
to be uploaded. Depending on how it is set up, the host system
may use the same filename that you enter in Step 4 below for
your system and not require that you enter the filename twice.
(On SPACE, the upload filename is required if you use ZDOOR-A,
but is not required when you use ZDOOR-B.)

3. When the host sytem tells you that it is ready to receive ZMODEM,
press ALT-F4 to shell to DOS (using Procomm). If you are using
a different communications program, consult your manual for the
command that will allow you to shell to DOS.

4. You will get a DOS prompt when invoke the shell. At the DOS
prompt, enter:
> SZ filespec(s)
where 'filespec(s)' is the file(s) you want to upload. (If the
host supports batch mode transfers, you will be prompted accord-
ingly and can use wildcards (* and ?) in your filespec.) If the
file(s) is not in the current DOS directory, you will need to
specify the path(s) as well as the filename(s).

5. When the upload is complete, you will be returned automatically
to Procomm (or the communications program you are using) ready
to respond to the next prompt of the host system.


DOWNLOADING FILES WITH ZMODEM
==============================
To download (receive) files from the host (BBS) system using Zmodem:

1. Select Zmodem protocol on the host system

2. When prompted by the host system, enter the name of the file(s)
to be downloaded. (If the host supports batch mode transfers or
wildcard filespecs, you will be prompted accordingly.)

3. When the host sytem tells you that it is ready to send ZMODEM,
press ALT-F4 to shell to DOS (using Procomm). If you are using
a different communications program, consult your manual for the
command that will allow you to shell to DOS.

4. You will get a DOS prompt when invoke the shell. At the DOS
prompt, first (if necessary) change directory to the directory
where you want the downloaded file(s) to be written when it is
received, and then enter:
> RZ
The filename(s) will be sent by the host system; you do NOT enter
them in your system. The file(s) will be written in your current
DOS directory as received.

5. When the download is complete, you will be returned automatically
to Procomm (or the communications program you are using) ready
to respond to the next prompt of the host system.
