T Select tone dialing
This command instructs the modem to send DTMF tones while dialing.
Dialed digits are tone dialed until a P command or dial modifier is
received. This is the default setting.
Vn DCE response format
This command controls whether result codes (including call progress
and negotiation progress messages) are displayed as words or their
numeric equivalents.
V0Displays result codes as digits.
V1Displays result codes as text (default).
Result Codes:
OKn=0,1
ERROROtherwise

Dial tone detect
Disabled: The modem dials a call regardless of whether it detects a
dial tone.
Enabled: The modem dials only upon detection of a dial tone, and
disconnects the call if the dial tone is not detected within
10 seconds.
Busy tone detect
Disabled: The modem ignores any busy tones it receives.
Enabled: The modem monitors for busy tones.
Result Codes:
OKn=0,1,2,3,4,5
ERROROtherwise
Zn Recall stored profile
The modem performs a soft reset and restores (recalls) the configura-
tion profile according to the parameter supplied. If no parameter is
specified, zero is assumed. Either Z0 or Z1 restores the profile.
Result Codes:
OKn=0,1
ERROROtherwise
&Cn Data Carrier Detect (DCD) control
Data Carrier Detect is a signal from the modem to the computer
indicating that a carrier signal is being received from a remote modem.
DCD normally turns off when the modem no longer detects the carrier
signal. 
						

							Users Manual

&C0The state of the carrier from the remote modem is ignored.
DCD circuit is always on.
&C1DCD turns on when the remote modem’s carrier signal is
detected, and off when the carrier signal is not detected
(default).
Result Codes:
OKn=0,1
ERROROtherwise
&Dn DTR control
This command interprets how the modem responds to the state of the
DTR signal and changes to the DTR signal.
&D0Ignore. The modem ignores the true status of DTR and treats
it as always on. This should only be used if your communica-
tion software does not provide DTR to the modem
&D1If the DTR signal is not detected while in on-line data mode,
the modem enters command mode, issues an OK result code,
and remains connected.
&D2If the DTR signal is not detected while in on-line data mode,
the modem disconnects (default).
&D3Reset on the on-to-off DTR transition.
Result Codes:
OKn=0,1,2,3
ERROROtherwise
&F Load factory settings
This command loads the configuration stored and programmed at the
factory. This operation replaces all of the command options and the S-
register settings in the active configuration with factory values.
&FRecall factory setting as active configuration.

&Gn V.22bis guard tone control
This command determines which guard tone, if any, to transmit while
transmitting in the high band (answer mode). This command is only
used in V.22 and V.22bis mode. This option is not used in North
America and is for international use only.
&G0Guard tone disabled (default).
&G1Sets guard tone to 550 Hz.
&G2Sets guard tone to 1800 Hz.
Result Codes:
OKn=0,1,2

&Pn Select Pulse Dial Make/Break Ratio (WW)
&P0Selects 39% - 61% make/break ratio at 10 pulses per second.
&P1Selects 33% - 67% make/break ratio at 10 pulses per second.
&P2Selects 33% - 67% make/break ratio at 20 pulses per second.
Result Codes:
OKn=0,1,2
ERROROtherwise
&Tn Self-test commands
These tests can help to isolate problems if you experience periodic
data loss or random errors.

&T0  Abort. Stops any test in progress.
&T1  Local analog loop. This test verifies modem operation, as
well as the connection between the modem and computer.
Any data entered at the local DTE is modulated, then
demodulated, and returned to the local DTE. To work
properly, the modem must be off-line.
Result Codes:
OK   n=0
CONNECT  n=1
ERROR  Otherwise
&V Display Current Configuration
This comm and displays the current configuration of the mod em. If
nonvolatile m emory is supported the stored profil es are displayed  as
well.
&V   View profil es.
&W  Store current configuration
Saves the current (active) configuration (profile), including S-
Registers.
The current configuration comprises a list of storable parameters
illustrated in the  &V  command. These settings are restored to the
active configuration upon receiving a  Zn  command or at power up.
Refer to the  &V  command.
&W   Stores the current configuration.
&Zn=x  Store telephone number
This command is used to store up to four dialing strings in the
modem’s nonvolatile memory for later dialing. The format for the
command is  &Zn =“stored number” where n is the location 0-3 to
which the number should be written. The dial string may contain up to
34 characters. The ATDS=n command dials using the string stored in
location n.
Result codes:
OK   n=0, 1, 2, 3
ERROR  Otherwise

Nn Error control mode selection
This command determines the type of error control used by the modem
when sending or receiving data.
\N0Buffer mode. No error control.
\N1Direct mode.
\N2MNP or disconnect mode. The modem attempts to connect
using MNP2-4 error control procedures. If this fails, the
modem disconnects.
This is also known as MNP reliable mode.
\N3V.42, MNP, or buffered (default).
The modem attempts to connect in V.42 error control mode.
If this fails, it attempts to connect in MNP mode. If this fails,
it connects in buffer mode and continues operation. This is
also known as V.42/MNP auto reliable mode (same as &Q5).
\N4V.42 or disconnect. The modem attempts to connect in V.42
error control mode. If this fails, the modem disconnects.
\N5V.42. MNP or buffered (same as \N3).
\N7V.42. MNP or buffered (same as \N3).

OKn=0,1,2,3,4,5,7

%B View numbers in blacklist
If blacklisting is in effect, this command displays the numbers for
which the last call attempted in the past two hours failed. The ERROR
result code appears in regions that do not require blacklisting.
%Cn Data compression control
This command determines the operation of V.42bis and MNP class 5
data compression. On-line changes do not take effect until a disconnect
occurs first.
%C0V.42bis/MNP 5 disabled. No data compression.
%C3V.42bis/MNP 5 enabled. Data compression enabled (default).
Result Codes:
OKn=0,3

S-registers
S-registers contain the settings that determine how a number of functions of the
internal modem operate. For example, how many times to let the telephone ring
before the modem answers and how long to wait before it hangs up if a connec-
tion fails. You can also customize certain AT commands such as the escape
sequence and command line termination.
The contents of the registers are changed automatically when you modify
corresponding settings in your communication software. If you choose,
however, you can display and edit the contents of the registers manually when
the modem is in command mode. If the value is out of the acceptable range,
then an error is generated.
This chapter describes the settings for each S-register.
S-register values
The format for displaying the value of an S-register is:
ATSn?
where n is the register number. After you type in the register press Enter.
The format for modifying the value of an S-register is:
ATSn=r
where n is the register number, and r is the new register value. After you type in
the register and its new value press Enter.
NOTE: Some registers vary from one country/region to another.

S0 Auto answer ring number
This register determines the number of rings the modem will count
before automatically answering a call. Enter 0 (zero) if you do not
want the modem to automatically answer at all. When disabled, the
modem can only answer with an ATA command.
Range: 0-255
Default: 0
Units: rings
S1 Ring counter
This register is read only. The value of S1 is incremented with each
ring. If no ring occurs over a six-second interval, this register is
cleared.
Range: 0-225
Default: 0
Units: rings
S2 AT escape character (user defined)
This register determines the ASCII values used for an escape
sequence. The default is the + character. The escape sequence allows
the modem to exit data mode and enter command mode when on-line.
Values greater than 127 disable the escape sequence.
Range: 0-255, ASCII decimal
Default: 4 3
Units: ASCII
S3 Command line termination character
This register determines the ASCII values as the carriage return
character. This character is used to end command lines and result
codes.
Range: 0-127, ASCII decimal
Default: 13 (carriage return)
Units: ASCII
