Chapter 6 – Voice Commands

Command:

+VNH=<hook><Enter>

Automatic Hang-Up Control

Values:

0, 1, 2, 3–255

 

 

Result Codes:

OK if command accepted; ERROR if parameter out of range.

Description:

The +VNH command causes the modem to enable or disable automatic hang ups to a varying

 

degree when in Data mode or Fax mode, as shown below:

 

+VNH=0

Enable automatic hang-ups as is normal in other non-Voice modes (such as

 

 

hanging up the phone when the modem does not detect a data carrier within a

 

 

given time interval).

 

 

+VNH=1

Disable automatic hang-ups in other non-Voice modes

 

+VNH=2

Disable automatic hang-ups in other non-Voice modes. The modem performs only

 

 

a "logical" hang up (i.e., returns the OK result code).

 

+VNH=3-255 Reserved for future standards

Command:

+FMI?<Enter>

 

Report Manufacturer's ID

Values:

n/a

 

 

Default:

n/a

 

 

Result Codes:

Only unsolicited result codes (not the standard AT -type OK result code)

Description:

The + FMI? command causes the modem to report text consisting of a single line with the modem

 

manufacturer's name (e.g., Lucent Data/Fax/Voice), and our address, phone, and fax numbers.

Command:

+FMM?<Enter>

Report Product ID

Result Codes:

Only unsolicited result codes (not the standard AT -type OK result code)

Description:

The +FMM command causes the modem to report text consisting of a single line with the modem's

 

name (e.g., SocketModem).

 

Command:

+FMR?<Enter>

Report Version Level

Result Codes:

OK or ERROR

 

 

Description:

The +FMR command causes the modem to report the firmware version number and/or a date code

 

(e.g., Vs. 2.07 – 2/4/95).

 

Command:

+FLO=<method><Enter>

Select Flow Control Method

Values:

0, 1, 2, 3–255Result Codes:

OK, or ERROR

Description:

The +FLO? command lets you select the method of flow control provided and used by the modem.

 

If +FLO=0, some other method (such as credit flow control) is used. The Xon-Xoff method is

 

required. Xon is the ASCII character <DC1> (11 hex). Xoff is the ASCII character >DC3> (13 hex).

 

CCITT V.24 circuits 106 and 133 are optional flow control methods. If circuits 106 and 133 are not

 

used (+FLO<>2), then circuit 106 is held On whenever +FCLASS=8. In Voice mode, circuit 105 has

 

no effect on the state of transmitted data. (Circuit 133 normally reverts to use as circuit 105 (RTS)

 

when not used for Flow Control.)

 

 

+FLO=0

Disable Xon-Xoff and 133/105 flow control

 

+FLO=1

Enable Xon-Xoff flow control in either direction

 

+FLO=2

Enable CCITT Circuit 133 for flow control of the modem by the PC; use CCITT

 

 

Circuit 106 for flow control of the PC by the modem.

 

+FLO=3-255 Reserved for future standards

Command:

VIP

 

Initialize Voice Parameters

Values:

0 (optional)

 

 

Description:

The +VIP command causes the modem to initialize all Voice parameters to the factory default

 

settings. This command has the same effect as if the PC had issued commands for the individual

parameter settings. The +VIP command has no effect on the +FCLASS setting. The optional command +VIP=0 <Enter> provides a selection of default profiles.
