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.
