Data Mode AT COMMANDS

Table 18. Data Mode Command Descriptions (Continued)

Command	Default		Description
T	none	Select Tone Dialing: This command configures the modem to use DTMF tones the next time the
		modem dials a telephone number (touch tone dialing).
		Result Code Form: This command selects whether the modem’s basic syntax response codes are in
Vn	1	numeric or verbose form.
		n = 0	Numeric form
		n = 1*	Text form
		Response Code Data Rate: This command selects whether the modem sends the DTE independent
		modem connection extended syntax result codes for modulation mode, speed, error control protocol, or
		data compression before the final 'CONNECT' message. This command does the selection by enabling
		and disabling the appropriate V.250 reporting commands (+MR, +ER, +DR, and +ILRR).
		n = 0*, 1	CONNECT result code reports DTE speed.
			For example:
			+ILRR: 115200
			CONNECT 50666
		n = 2	CONNECT result code reports modulation mode and DCE transmitter speed.
			For example:
			+MCR: V90
			+MRR: 28800
			CONNECT 50666
		n = 3	CONNECT result code reports DTE data rate, modulation mode, error correction, data
			compression, DCE transmitter speed and DCE receiver speed.
Wn	0		For example:
			+MCR: V90
			+MRR: 28800
			+ER: LAPM
			+DR: V42B
			+ILRR: 115200
			CONNECT 50666
		n = 4	CONNECT result code reports modulation mode, error correction, data compression, DCE
			transmitter speed and DCE receiver speed.
			For example:
			+MCR: V90
			+MRR: 28800
			+ER: LAPM
			+DR: V42B
			CONNECT 50666
			Please refer to +MR=m, +ER=m, +DR=m and +ILRR=m for a detailed description of each
			command.
		Result Code Type/Call Progress: This command determines which modem result codes are enabled.
		Additionally, this command specifies whether busy and dial tone detection are enabled or disabled.
		n = 0	Result codes 0–4 enabled. Busy and dial tone detect disabled.
		n = 1	Result codes 0–5, 10 and above enabled. Busy and dial tone detect disabled.
Xn	4	n = 2	Result codes 0–6, 10 and above enabled. Busy detect disabled and dial tone detect
			enabled.
		n = 3	Result codes 0–5, 7, 10 and above enabled. Busy detect enabled and dial tone detect
			disabled.
		n = 4*	Result codes 0–7, 10 and above enabled. Busy and dial tone detect enabled.

NOTE: An asterisk (*) denotes the factory-default setting.
