	Chapter 7 – Voice Commands
Command: +VDT	Control Tone Cadence Reporting
Description:	his command is included for compatibility only and has no effect other than
	returning a result code.
	This command allows the modem to enable or disable reporting of the control
	tone cadence information in the frequency band used by the
	Ringback/Remote Ring, BUSY, and reorder/Fast Busy tones (usually in the

300to 600 Hz range).

Syntax:+VDT=<enable>,<report>

Defined Values:	<enable> Decimal number corresponding to the selected option.
	0 The modem will not produce any control tone cadence report.
	<report> Decimal number specifying the produced any control tone cadence
	report when enabled by the <enable> subparameter.
	0 The modem will produce only CPOF and CPON messages.

Other Reserved.

Reporting Current or Selected Values:

Command: +VDT?

Response: <enable>,<report>

Example: 0,0 For the default setting.

Reporting Supported Range of Parameter Values:

Command: +VDT=?

Response: (<enable> range),(<report> range)

Example: (0),(0)

Result Codes:OK <enable>,<report> = (0),(0)

ERROR Otherwise, or if not in Voice Mode.

Command: +VPR	Select DTE/Modem Interface Rate (Turn Off Autobaud)
Description:	This command selects the DTE/modem interface rate.
Syntax:	+VPR=<rate>
Defined Values:	<rate>> Decimal number corresponding to the DTE/modem interface rate
	where 0 = autobaud rate determined by processing the AT command, and
	1,2,3,4,8,16,24,48,96 correspond to multipliers of 2400 bps to determine the
	actual rate:
	0	= Autobaud
	1	= 2400 bps
	2	= 4800 bps
	3	= 7200 bps
	4	= 9600 bps
	8	= 19200 bps
	16 = 38400 bps
	24 = 57600 bps
	48 = 115200 bps
	96 = 230400 bps
Reporting Current or Selected Values:
	Command: +VPR?
	Response: <rate>

	Example: 0 For the default setting (Autobaud).
Reporting Supported Range of Parameter Values:
	Command: +VPR=?
	Response: (<rate> range)
	Example: (0,1,2,3,4,8,16,24,48,96)
Result Codes:	OK <rate> = 0,1,2,3,4,8,16,24,48,96.
	ERROR Otherwise, or if not in Voice Mode.
