Express ZModem Receive(EZRECV) Program
July 1, 1992
Version 1.0
EZRECV is a DOS program which was developed for the purpose
of providing an easy automatic receive capability for the
transfer of computer information using modems. The driving
concept was that belief that computer to computer data
communications should be as easy as FAX transmissions.
EZRECV provides an automatic background ZModem file transfer
capability. The program waits for a computer to call,
receives a file from the other computer, and then terminates
the connection. The files are stored in a subdirectory off
of the program directory called "INBOX".
EZRECV addresses two issues which have limited the spread of
easy computer to computer information transfer. The first
is the lack of background file transfer capability. Ordinary
communications programs offer host mode operation, however
the programs run in the foreground. Even in cases where
the user can allocate a PC to the function the program must
be stopped in order to do anything with the received files.
By operating in the background, EZRECV allows users to access
the received files while transfers are occuring.
The second issue is protocol. Some proprietary file
transfer programs are available to send and receive files in
the background. However they typically use a proprietary
protocol to perform the transfer. The user must buy and
install software for both machines to use these programs.
Because no one vendor has developed a standard accepted by
the industry it is impossible to provide widespread transfer
capability. By using ZModem transfer protocols, EZRECV allows
most computers to send files to the receiving computer using
their existing modem communications software. This limits
the expense and guarantees almost universal access. Use of
another protocol such as XModem would have provided even broader
access, however XMODEM suffers from several technical issues
which limit its utility in a general purpose transfer program.
EZRECV is a shareware program. The user is allowed to try
out the program before registering. If the user continues to
use the program, it must be registered. Registration entitles
the user to the latest version of the software, technical
support, access to the Express BBS, and notification of future
product upgrades.
Future upgrades could address areas such as support for
higher speed modems, host identification, multiple file
transmission capability, and reduced program size.
Registration will drive the addition of these features.
Additionally other related programs will be introduced to
provide better management of the received files.
Installation
This distribution consists of two programs.
EESETUP is used to define the basic system configuration
for EZRECV.
EZRECV is the background file transfer program.
Installation of the software consists of the following
steps. The commands assume that the software will be
installed on the C: drive, and that the software is
distributed on a floppy disk in the A: drive. If this
is not the case, modify the following statements to
handle your configuration.
Step 1: Create a directory for the program.
C:\>MD EE
Step 2: Change to the new directory.
C:\>CD EE
Step 3: Copy the files to the new directory.
C:\EE>COPY A:*.*
Step 4: Create the directory for incoming files.
C:\EE>MD INBOX
Step 5: Configure the program for your system by
running EESETUP.
C:\EE>EESETUP
A: Specify the COM port used for the modem.
Valid choices are 1 and 2 for COM1 and COM2
respectively.
B: Specify the incoming phone number, including
area code.
C: Specify the modem reset string. Default is
'Z'.
D: Specify the modem initialization string.
This is important. The information needed
for this string is usually contained in the
modem user manual.
Step 6: Run EZRECV. This must be executed from within the
program directory.
C:\EE>EZRECV
That's all there is to it. If you want to remove EZRECV from
memory, type EZRECV -r at the command prompt. Note that this
only works if no background programs were loaded into memory
after EZRECV was installed.
Transferring a file to a machine with EZRECV is easy. After
receiving an incoming call, EZRECV is awaiting a file transfer.
The transmitting system will only see some spurious characters
which is part of the ZMODEM protocol. The transmitting system
should begin transfer immediately. At the completion of the
transfer, EZRECV disconnects and waits for the next call.
Disclaimer
Users of EZRECV agree to the following discaimer of warranty
before useing the software. EZRECV is provided as is. The

Ordering
Express ZModem Receive(EZRECV) version 1.0 is a shareware
program. You may use it for a period of up to 30 days to
evaluate its usefulness to you. If you wish to continue
using it you must register it. Registration entitles you to
the latest version of the software, access to the Express BBS,
and free technical support. The software may be shipped,
or at your request transmitted directly to you at your EZRECV
phone number. The registration fee is $29. This includes
shipping, but does not include sales tax. California residents
must include 8.25% sales tax. Corporate multi-site licences are
also available. Send checks to:
