MODEMSETTINGS info  Overview  Group

The MODEMSETTINGS structure contains information about a modemís configuration.

typedef struct modemsettings_tag {
DWORD dwActualSize; // size of returned data, in bytes
DWORD dwRequiredSize; // total size of structure
DWORD dwDevSpecificOffset; // offset of provider-defined data
DWORD dwDevSpecificSize; // size of provider-defined data

// Static local options (read/write)
DWORD dwCallSetupFailTimer; // call setup timeout, in seconds
DWORD dwInactivityTimeout; // inactivity timeout, in tenths of seconds
DWORD dwSpeakerVolume; // speaker volume level
DWORD dwSpeakerMode; // speaker mode
DWORD dwPreferredModemOptions; // bitmap specifying preferred options

// negotiated options (read only) for current or last call
DWORD dwNegotiatedModemOptions; // bitmap specifying actual options
DWORD dwNegotiatedDCERate; // DCE rate, in bits per second

// Variable portion for proprietary expansion
BYTE abVariablePortion[1]; // variable-length data
} MODEMSETTINGS, *PMODEMSETTINGS, *LPMODEMSETTINGS;

Members

dwActualSize
Specifies the size, in bytes, of the data actually returned to the application. This member may be less than the dwRequiredSize member if an application did not allocate enough space for the variable-length portion of the structure.
dwRequiredSize
Specifies the number of bytes required for the entire MODEMDEVCAPS structure, including the variable-length portion.
dwDevSpecificOffset
Specifies the offset of the provider-defined portion of the structure, in bytes relative to the beginning of the structure.
dwDevSpecificSize
Specifies the size of the provider-defined portion of the structure, in bytes.
dwCallSetupFailTimer
Specifies the maximum number of seconds the modem should wait, after dialing is completed, for an indication that a modem-to-modem connection has been established. If a connection is not established in this interval, the call is assumed to have failed. This member is equivalent to register S7 in Hayes® compatible modems.
dwInactivityTimeout
Specifies the maximum number of seconds of inactivity allowed after a connection is established. If no data is either transmitted or received for this period of time, the call is automatically terminated. This time-out is used to avoid excessive long distance charges or online service charges if an application unexpectedly locks up or the user leaves.
dwSpeakerVolume
Specifies the volume level of the monitor speaker when the speaker is on. This member can be one of the following values:

Value

Meaning

MDMVOL_LOW

Low volume.

MDMVOL_MEDIUM

Medium volume.

MDMVOL_HIGH

High volume.

The MODEMDEVCAPS structure specifies the speaker volumes a modem supports. Actual volumes are hardware-specific.

dwSpeakerMode
Specifies when the speaker should be on. This member can be one of the following values:

Value

Meaning

MDMSPKR_OFF

The speaker is always off.

MDMSPKR_CALLSETUP

The speaker is on until a connection is established.

MDMSPKR_ON

The speaker is always on.

MDMSPKR_DIAL

The speaker is on until a connection is established, except that it is off while the modem is actually dialing.

dwPreferredModemOptions
Specifies the modem options requested by the application. The local and remote modems negotiate modem options during call setup; this member specifies the initial negotiating position of the local modem.

The dwModemOptions member of the MODEMDEVCAPSstructure specifies the modem options supported by the local modem. For a list of modem options, see the description of the MODEMDEVCAPS structure.

dwNegotiatedModemOptions
Specifies the modem options that are actually in effect. This member is filled in after a connection is established and the local and remote modems negotiate modem options.

The dwModemOptions member of the MODEMDEVCAPS structure specifies the modem options supported by the local modem. For a list of modem options, see the description of the MODEMDEVCAPS structure.

dwNegotiatedDCERate
Specifies the DCE rate that is in effect. This member is filled in after a connection is established and the local and remote modems negotiate modem modulations.
abVariablePortion
Contains provider-defined information, if any.
