ModemEngine, what is it, and what does it do
--------------------------------------------
The ModemEngine (ME for short) is a C++ interface to voice 
modems with the Rockwell RC14V***** chipsets. At this point of 
time it supports the voice AT command set (AT#****) but it was 
intended to support fax AT commands (AT+fclass****) as well. 
However, this is left as an exercise for the reader. The C++ 
interface makes it possible to record and play audio data with 
the modem making it suitable for e.g. answering machine pur-
poses.



ModemEngine, the specification
------------------------------
There is none. I have yet to find the time to write it, 
therefore the working of the ME is illustrated in the supplied 
sample, and the voice modem's working is documented in the 
supplied documentation (DOC.ZIP). The included sample is the 
new answering machine in progress, but it is far from done. It 
shows the use of the ME in some routines (e.g. testing the 
modem's compatibility).



ModemEngine, who made it, and why
---------------------------------
ME is made by me, Sacha Prins.

I can be reached by mail: sprins@businessnet.net or 
100417.1437@compuserve.com

Once upon a time I got a 14.4 voice/fax modem and found out 
that there wasn't any OS/2 software for it. Being a university 
student with time to spare, I made an OS/2 prototype of an 
answering machine (distributed as ANS106p.ZIP) that did just 
that, answer calls. Since it really is a prototype I found out 
that is wasn't expandable, due to the `spaghetti' nature of 
the code. Therefore I started from scratch and made a C++ 
class to encapsulate the modems control. In the meantime I 
graduated. I also have to work for my money nowadays, and 
since I have my own business, my time is very scarce.



ModemEngine, who is it for
--------------------------
Anyone interested in making his/her voice modem work with OS/2 
that has programming experience with C++. Since the documen-
tation is very thin (this is it) some investigation is also 
required. Sample programs in this package should illustrate 
the working of ME.



ModemEngine, the package
------------------------
The package is a source distribution only. The reason is that 
ME is intended for developers only.

The package consists of the following files:

DEF.DEF             the DLL definition file
doc.zip             Rockwell voice modem docs
license.txt         Licence of this package
readme.txt          This file
Makefile            Makefile of the DLL
ModemEngine.cpp     C++ source of ME.DLL
ModemEngine.Dep     dependencies file of the makefile
ModemEngine.h       header file used by the C++ source
ModemEngine.hpp     ME class interface, to be #included             
                     in your sources.
sample.zip          Answering machine to be. Illustrates  
                     the  use of ME.DLL
file_id.diz         BBS info file
