                             Chapter 1 Introduction

     This package of asynchronous communications tools for IBM (COM1 - COM4)
and Digiboard (intelligent communications hardware, up to 32 ports) hardware,
consists of library (.LIB) files for each memory model and for both IBM and
Digiboard hardware.  It also includes all of the source files, header files
(with prototypes) and MAKE files needed to generate the various libraries.
Batch files are included for calling make with appropriate flags for each
supported compiler.

     This "shareware" version is configured for the BORLANDC compiler in
.LIB format, and comes with the small memory model library only (ASYNCS.LIB).
Header files with module prototypes for the library routines are included, as
well as TEST.C for testing the modules on your system. No other source code is
provided with the shareware version or support for Digiboard hardware.
Shareware versions are also available for MSC 6.0.

     Also included are useful demonstration utilities as described in the
manual.

     A working knowledge of 'C' and operation of your compiler is assumed.

     Becoming a registered user will provide full source code to every module,
make files, support for other C compilers (Zortech, MSC, QuickC), 3 more
utility programs, and a bound laser printed manual. There is also full support
for Digiboard communications boards which will allow up to 32 ports on your PC.
You will also be put on our registered users list and receive upgrade
notification whenever new, expanded versions become available.

     You can pay with Visa or Mastercard.  Provide your card number and 
expiration date.  Make sure you include the spelling of the name on the Visa
or Mastercard.  Please include your shipping address.

     If you desire to use these tools as is, have no need for the source code,
Digiboard support, or a printed manual, then a fee of $15 should be sent to the
above address.  This will also put you on our mailing list for announcements of
other products/upgraded versions.

                          HERE'S HOW SHAREWARE WORKS:

     You are encouraged to copy ASYNC30B.ZIP file and share it freely with
others. You have the luxury of trying out the library and DATAMON program at
your own pace and in the comfort of your own home or workplace.

     If, after trying out the library, you decide to continue to use them, you
are trusted to purchase the Asynchronous Toolbox from the program's author, or
from an authorized dealer.

     Why pay at all?

     * You receive a CURRENT copy of the program
     * You receive a laser printed manual
     * One year of technical support - by phone or written
     * Notification of updates (and fixes, if required)
     * Inexpensive upgrade offers
     * Notification of new products
     * Periodic offers and "deals" (for our customers only)
     * Your input and ideas help shape future product

     * A sense of pride and ownership, in having honestly participated in the
     Shareware revolution

     * You help to keep software prices down, by supporting a distribution
     method which doesn't rely on expensive advertising campaigns.

     So please dive in and enjoy the fun of legally sharing good software with
your friends and associates. But also be aware of the following restrictions,
designed to protect the community of Shareware users and authors, and to
prevent greedy people from taking unfair advantage of the trust, hard work, and
good will of Shareware authors:

     1. No price or consideration may be charged. However, a distribution cost
may be charged for the cost of the diskettes, shipping, and handling, not to
exceed $10 total.

     2. You may use the libraries to create your own programs with no licensing
fee.

     3. You may modify any of the source programs or use part of them to create
your own programs. You may not make minor changes and then sell the new
version.  4. The programs cannot be "rented" or "leased" to others.

     5. The printed manual cannot be copied or reproduced in any way.[PB]

                             Chapter 2 Installation

2.1 Shareware Version

     The shareware version contains only the BORLANDC V2.0 small memory model
library (ASYNCS.LIB), include files (*.h), and DATAMON.EXE (a nifty data line
monitor program for debugging and testing RS-232 devices).  All files are
compressed together into ASYNC30B.ZIP.

     First copy ASYNC30B.ZIP to the subdirectory where your C source files are
kept.  Then type PKUNZIP ASYNC30B to uncompress the files.

     Copy ASYNCS.LIB to your \BORLANDC\LIB subdirectory.

     Copy *.H files to \BORLANDC\INCLUDE subdirectory.

     Print out the documentation for these tools (ASYNC.TXT).  ASYNC.TXT and
README (this file) can be printed by typing PRINT ASYNC.TXT (or README).

     The shareware manual is approximately 35 pages long.

     Follow instructions in the manual to test your installation with a simple
communications test program (TEST.C).
