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 utilise the single Dualwave-I 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. 
NoteDo NOT connect the modem to your iPAQ whilst 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:
