The SDK is available for the Win32-based platforms that are supported by the Nokia D211
itself (Windows 98SE, Windows Me, Windows 2000 and Windows XP). Support for Windows
CE and Linux cannot be confirmed at this point.
The following paragraphs give more technical details about the interface. There is only a
single interface that provides all the features available from Nokia D211. The Nokia D211
host OS service process that is installed as part of the Nokia D211 installation provides this
interface. The interface is provided using an asynchronous message-passing mechanism (a
utility library providing synchronous access is also provided). All requests for the Nokia D211
software need to be formulated into a service request such as REQ_PHONE_INFO (for
requesting phone information) for which response messages will be offered. In addition, an
application may register for indications from the Nokia D211 software, such as
IND_PHONE_CALL. There are numerous messages that are used to access the features of
the Nokia D211. For simplicity, they have been grouped into service sets that collect a set of
related service message definitions together. Below is a list of service sets available.
