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. The "shareware" version is configured for the MSC 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. 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. To register, fill out the following form and send a check for $45 to Nordtech Research, Inc. P.O.

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. HERE'S HOW SHAREWARE WORKS: You are encouraged to copy ASYNC30M.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.

All files are compressed together into ASYNC30M.ZIP. First copy ASYNC30M.ZIP to the subdirectory where your C source files are kept. Then type PKUNZIP ASYNC to uncompress the files. Copy ASYNCS.LIB to your \c600\LIB subdirectory. Copy *.H files to \c600\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).
