| Topic | Description |
|---|---|
The AbortPlay entry identifies the command that is issued to the modem to stop playing the audio data immediately. |
|
The BaudRate entry is used in the serial wave device INF file. It specifies the port speed. |
|
The BaudRate (NT Wavedriver) entry provides voice functionality for Windows 2000 and later versions of the operating system. It specifies port speed. |
|
The VoiceBaudRate entry specifies port speed prior to switching into voice mode with VoiceAnswer or VoiceDialNumberSetup. The BaudRate setting is used at the beginning of serial wave operation. |
|
The CallerIDPrivate and CallerIDOutSide entries identify the characters that the modem returns when it reports that Caller ID information was not sent. The information that is not sent might have been blocked (private) or out of the area. |
|
The EnableCallerID entry defines the AT command used to enable Caller ID reporting. |
|
The ForwardDelay entry specifies the delay in milliseconds between dialing the call-forwarding cancel code and hanging up. This entry also specifies the delay between dialing the call-forwarding dial string and hanging up. |
|
The GenerateDigit entry specifies the AT command that is used to generate a DTMF digit during a voice call. |
|
The HandsetCloseDelay entry specifies the amount of time, in seconds, that the CloseHandset command will be issued after a call to the Multimedia function waveClose. |

LineSetPlayFormat, LineSetRecordFormat, HandsetSetPlayFormat, HandsetSetRecordFormat |
The LineSetPlayFormat, LineSetRecordFormat, HandsetSetPlayFormat, and HandsetSetRecordFormat entries define commands that direct the modem to set the record/play format. |
The LowerMid, LowerWaveInPid, and LowerWaveOutPid entries appear in the wave wrapper INF file. These entries identify the audio wave driver's manufacturer ID and product ID for the wave wrapper. |
