The Virtual Device Driver (VDD) and Port Server are essentially
“middleware” software, which provides a layer of abstraction to
application developers so that communications with the modem can be
significantly simplified. They remove the requirement to fully
understand the Native Communication Language (NCL) syntax to
communicate with the modem.
In addition, the VDD and Port Server allows multiple applications (or
“sessions”) on the iPAQ Pocket PC to simultaneously interface with
different network host servers, such as an email client, web browser,
dispatch application or Modem Info itself. Messages are routed to the
appropriate application via the Microsoft Message Queue facility.
Third party application developers should refer to document “DWI
Modem Virtual Device Driver and Application Interface”
(DWI10010WTxx) for further information.
If multi-session capability is not required, the VDD and Port Server
CAB file does not need to be installed, however, Modem Info requires
this middleware software in order to operate.

The Microsoft Message Queue (MSMQ) allows multiple applications
(or sessions) to simultaneously utilize the single non-rugged PRM240i
modem in which an iPAQ is inserted. It is the mechanism by which
information is routed between the appropriate application on the iPAQ
Pocket PC and the network host server.
Installing the Modem Software To install the CAB files onto your iPAQ, ensure that the iPAQ desktop
software has been installed on your computer first and then use the
following procedure.
Note: Do NOT connect the modem to your iPAQ while installing the
CAB files.
1. Connect the auto-sync cable (supplied with your iPAQ),
between the iPAQ and the corresponding port on your PC or
use the iPAQ cradle.
2. Switch the PC on and insert the CD-ROM, which was supplied
with your modem, into your CD-ROM drive.
3. Locate the three CAB files on the CDROM using Microsoft
Explorer.
4. From your PC, copy and paste the three CAB files into the
Mobile Device/My Pocket PC/Temp folder as shown in the
following diagram:
