Additional information
The most comprehensive resource for MWave adapters on the Internet is the Unofficial MWave home page. For information on drivers and using MWave cards for audio, take a look at Rod Smith's OS/2 Soundcard Summary.

Detecting an MWave modem
MWave adapters are multi-purpose DSP devices (sound card, modem, and TAM). The biggest giveaway that you have an MWave adapter is that you had to install drivers for each of these functions! However, if you are still in doubt, start a terminal program (e.g. HyperAccess Lite) and type:

ati3
ati4

You should get output something like:

ati3
IBM Mwave Modem v3.0
OK
ati4
Generic Mwave
OK

What is the main advantage of MWave modems over other voice modems?
Because all MWave functions are dynamically loaded in software, an MWave modem can dedicate more resources to voice functions than other kinds of modems. Therefore, the voice recording and playback quality achieved with an MWave modem is usually superior.

One disadvantage of an MWave modem is that it is only possible to install a single modem in a PC, so MWave is not suitable for multi-line applications.
Why does FaxWorks for OS/2 not support MWave modems?
Keller Group say:
IBM has only provided a subset of the Windows MWave functionality on OS/2, and they neglected to provide the calls for playing and recording Wave audio on the telephone. (Read the full text here.)

Essentially what this means is that under OS/2, it is only possible to play and record telephone messages using IBM's proprietary voice format. Under Windows, IBM have provided routines to do on-the-fly conversion from standard formats such as WAV or ADPCM. Keller Group object to the fact that there is no portable/hardware independent way to record and play voice messages under OS/2. The article concludes:
If and when IBM provides OS/2 drivers which match the standard features of the Windows MWave drivers, then we can support voice with OS/2 MWave. But until then, we're stuck. Please help us by telling IBM that they should provide full OS/2 support for the MWave hardware by completing the Wave file telephone functions.

a CONFIG.SYS section that works:

BASEDEV=VHDO0437.SYS BUS=1150000

REM ** MWave 3780i ACP Modem
SET MWFT_PATHNAME=D:\OS2APPS\Mwave\DSP
SET MWPATH=D:\OS2APPS\Mwave\DSP;D:\OS2APPS\Mwave\MWAVEOS;
SET MWCARD=Modem
SET MWROOT=D:\OS2APPS\Mwave
SET MWOSNAME=MWOS3780.DSP
SET MWBIOS=MWBI0917.DSP
DEVICE=D:\OS2APPS\Mwave\BIN\MWAVEDD.SYS
DEVICE=D:\OS2APPS\Mwave\BIN\MEIO0437.SYS
RUN=D:\OS2APPS\Mwave\BIN\MWSTART.EXE

The MWave directory should also be present in LIBPATH, PATH, DPATH, HELP
and BOOKSHELF in the usual way. And for modem to actually work, the GUI
applet MWMOS2.EXE should be started from within PM.
