UNIMODEM V FUNCTIONALITY
========================

Unimodem V is the newest release of Unimodem, the Windows universal
modem driver/telephony service provider for data/fax modems. Unimodem V 
adds the most commonly requested features to support data/fax/voice 
modems, including wave playback and recording to and from the phone line, 
wave playback and recording to and from the handset, and support for 
speakerphones, caller ID, distinctive ringing, and call forwarding. 

This release provides .inf files for some specific modems; however, 
Unimodem V provides base support, with the addition of an .inf file, 
for any voice modem based on one of the specific supported chipsets 
(Rockwell, Cirrus, AT&T) or any other AT+V/AT#V standard modem. Support 
for Sierra chipsets is in progress and will be available soon.
Information on the process for creating .inf files can be found on 
ftp.microsoft.com in the developr\drg\modem directory.

The Unimodem V specification, which describes new features and what you 
need to know about wave drivers, is located on CompuServe® on the WINEXT 
forum, Library Section 3 (TAPI SDK), and on the Microsoft ftp site 
(ftp.microsoft.com or 198.105.232.1) in the \Developer\Tapi directory.

The Unimodem V software consists of the following parts:

1. The Unimodem V Telephony Service Provider (TSP) and VxD. The TSP 
   handles program requests, such as dialing and answering, which are 
   passed down from TAPI. The TSP hides modem-specific details of how 
   telephony operations, such as dialing, are handled. The VxD is called 
   by the TSP to send command strings to the modem. It is called by the 
   VCOMM VxD to change modem settings and send/receive data to/from the 
   modem.

2. Operator Agent, a program that identifies whether an incoming call is 
   from a person, a fax machine, or a data modem. It then forwards the 
   call to the appropriate program, such as the answering machine or fax 
   program. If Operator Agent can’t automatically determine the type of 
   call, it asks the caller to identify it. If the caller cannot identify 
   it, Operator Agent forwards the call to a program specified by the user. 

   To start Operator Agent, click the Start button, point to Programs, 
   point to Accessories, and then click Operator. When Operator Agent is 
   running, an icon appears on the taskbar near the clock. 

3. A wave driver for serial port modems that supports the following 
   formats: IMA ADPCM at 4800 kHz, 7200 kHz, or 8000 kHz; and Rockwell 
   ADPCM.

4. A wave wrapper for use with modems with a separate audio hardware 
   interface, where synchronization is needed between the modem and audio 
   via AT commands. The wave wrapper is called by MMSystem, and it calls 
   Unimodem V to send any needed AT commands to the modem. After the AT 
   commands are complete, the wave wrapper calls back into MMSystem, and 
   MSystem then calls the modem wave device. The modem wave device 
   interfaces only with the audio hardware interface.

5. A wave driver for the Compaq Presario, which uses the wave wrapper.

6. The following .inf files for modems currently supported by Unimodem V:

   mdmcpq.inf	   Compaq Presario models 520, 720, 820, and 920
   tamwrap.inf 	   Presario wave driver and wrapper
   mdmdsi.inf	   Creative Labs Phone Blaster
   mdmrock.inf	   Logicode 14.4 data/fax/voice PCMCIA
   mdmrock2.inf	   Diamond Multimedia TeleCommander 2500
   mdmrock2.inf	   Cirrus Logic
   mdmrock3.inf	   Aztech Systems
   mdmrock4.inf	   Rockwell PCMCIA reference design


INSTALLING THE UNIMODEM V SOFTWARE
==================================

To install Unimodem V, you must have a PC running Microsoft® Windows® 95. 
These instructions assume that you have already successfully installed 
the modem hardware according to the manufacturer’s instructions.

To install Unimodem V software, carry out the following steps: 

1. Run Unimodv.exe, which will automatically extract all files into the 
   directory you specify (\Dirname).
2. In \Dirname, right-click the file Unimodv.inf, and then click Install.
3. Restart your computer.
4. In Control Panel, double-click the System icon, and then click the 
   Device Manager tab.
5. Double-click the Modem icon.
6. In the list, click your modem, and then click Remove.
7. Click Refresh.

If the modem is Plug and Play, Windows 95 automatically detects the 
modem. If the modem is not automatically detected, carry out these 
additional steps:

1. In Control Panel, double-click the Modems icon.
2. If the Install New Modem wizard does not automatically start, click 
   Add.
3. Follow the instructions on your screen to detect your modem.

NOTE: Installation of Unimodem V replaces the following Windows 95 
      components:

      Unimodem.vxd
      Unimdm.tsp
      Umdm16.dll
      Umdm32.dll

If you remove Unimodem V from your computer at some point and want to 
restore these files, the easiest way to do so is to reinstall Windows 95.

KNOWN PROBLEMS
==============

Running the Operator Agent with DATA and FAX applications
---------------------------------------------------------
If the Operator Agent is run with only DATA and FAX media mode
applications running, the Operator Agent will not work correctly.
If a VOICE media mode application is running with DATA and/or FAX,
the Operator Agent will work correctly.  We are working on a fix
for this problem.
