Code Sample Name: CeDialer

Feature Area: Cellcore.

Description: 

    To simplify the process of using a modem, Windows CE provides an 
    implementation of the Microsoft Telephony API (TAPI). The CEDialer code 
    sample shows how to dial a call with a modem using TAPI functions.

    Windows CE TAPI supports outbound calls, but does not support inbound calls.
    TAPI also supports installable service providers. The Telephony Service 
    Provider Interface (TSPI) enables developers to create telephony service 
    applications that handle function calls from remote applications to carry 
    out and control communications over the telephone network. 

    In Windows CE, TAPI links to and calls TSPI functions using standard 
    dynamic-link library (DLL) functions. TAPI uses the Unimodem TSPI by default. 

Relevant APIs: 
    lineInitialize, lineNegotiateAPIVersion, lineGetDevCaps, lineDrop, 
    lineDeallocateCall, lineClose.

Usage:

    Using TAPI to make a modem call
    A Windows CE朾ased application that uses a modem must be able to handle 
    tasks such as initializing the modem, opening the line, dialing a phone 
    number, and disconnecting when the session is complete.

    The following are the main steps and associated functions for dialing a call 
    in CEDialer:
