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 the Microsoft ftp site (ftp.microsoft.com or 207.46.133.140) in the \Developr\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(r) Windows(r) 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.
