Data Mode AT COMMANDS

Table 18. Data Mode Command Descriptions (Continued)

Command

Default

 

Description

 

 

 

 

 

Dial Command: This command causes the modem to immediately go off-hook as an originating modem

 

 

and dial a telephone number with corresponding dial modifiers. Dial modifiers are parameters that define

 

 

how the modem should dial the telephone number.

 

 

Dial Modifiers

 

 

0–9

Dialing Digits

 

 

A, B, C,

Tone Dial Characters

 

 

D, *, #

 

 

 

P

Pulse Dial—configures the modem to use pulse dialing to dial a telephone number.

 

 

R

Reverse Originate Mode—places the modem in answer mode. This modifier should be the

 

 

 

last character in the dialing string (for example, ATDT 12345678R). After dialing the

 

 

 

telephone number, the modem goes into data modem answer mode instead of originate

 

 

 

mode.

 

 

S = n

Dial NVRAM Telephone Number—causes the modem to dial a telephone number

D

none

 

previously stored in the NVRAM with the AT&Zn=x command.

T

Tone Dial—configures the modem to use DTMF tones to dial a telephone number.

 

 

 

 

W

Wait for Dial Tone—causes the modem to look for dial tone for a specified amount of time.

 

 

 

If dial tone or the amount of time specified by the S-register, S6, times out, the modem

 

 

 

processes the next command in the dial string. If a busy signal is detected, the modem

 

 

 

responds to the DTE with a busy response code and then goes into off-line command

 

 

 

mode.

 

 

,

Pause—causes the modem to pause or delay implementing the next parameter in the dial

 

 

 

string by the time specified in S-register S8.

 

 

!

Flash Hook—causes the modem to go on-hook for 0.75 seconds.

 

 

@

Wait for Quiet Answer—causes the modem to wait for specified amount of time (S-register

 

 

 

S7) followed by 5 seconds of silence before processing the next dial modifier.

 

 

;

Return to Idle State—causes the modem to enter online command mode without initiating a

 

 

 

data modem handshake (used for phone directory auto-dialers).

 

 

<space> - ( ) Ignored by Modem—these four characters are ignored by the modem. Spaces also may be

 

 

 

included in the dial string to separate area codes and numbers.

 

 

 

 

 

Command Mode Echo: This command selects whether the modem echoes AT commands back to the

En

1

host in either online or off-line command mode.

n = 0

Echo disabled

 

 

 

 

n = 1*

Echo enabled

 

 

 

 

 

Switch Hook Control: This command controls the telephone line relay (OHREL*) and causes the

Hn

0

modem to either hang up or pick up the telephone line.

n = 0*

Hang up telephone line (go on-hook)

 

 

 

 

n = 1

Pick up telephone line (go off-hook)

 

 

 

 

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