Basic AT Command Guide
T - Set Tone Dial Default
This command forces DTMF dialing until the next P dial modifier or P command is received. The
modem will set an S-Parameter bit to indicate that all subsequent dialing should be conducted in
tone mode. Note that the DP command will override this command. Clears S14 bit 5.
This command may not be permitted in some countries. (See P.)
Syntax
T
Result Codes
OK
P - Set Pulse Dial Default
This command forces pulse dialing until the next T dial modifier or T command is received. Sets
S14 bit 5.
As soon as a dial command is executed which explicitly specifies the dialing mode for that
particular call (e.g., ATDT..), this command is overridden so that all future dialing will be tone
dialed. (See T command.)
This command may not be permitted in some countries.
A - Answer The modem will go off-hook and will attempt to answer an incoming call if correct
conditions are met. Upon successful completion of answer handshake, the modem will go on-line
in answer mode. This command may be affected by the state of Line Current Sense, if enabled.
(Most countries do not require Line Current Sense.) Operation is also dependent upon +FCLASS
command and country-specific requirements. If +FCLASS=0 is selected, the modem will enter
the connect state after exchanging carrier with the remote modem. If no carrier is detected within
a period specified in register S7, the modem will hang up. Any character entered during the
connect sequence will abort the connection attempt.
If +FCLASS=1.0 is selected, the modem will go off-hook in V.21 answer mode. It will generate the
V.21 2100 Hz answer tone for 3 ± 0.5 seconds. Following a delay of 70 ms, it will proceed as if the
+FTH=3 command were issued. At any stage up to (but excluding) the +FTH=3 command state,
anycharacter will abort the communication. (See the description of the +FTH command for
details.)
H - Disconnect (Hang-Up)
This command initiates a hang up sequence. This command may not be available for some
countries
due to PTT restrictions.
Syntax
H[<value>]
Defined Values
<value> Decimal number corresponding to the selected option.
0 The modem will release the line if the modem is currently on-line.
1 If on-hook, the modem will go off-hook and remain in command mode.

Result Codes
OK <value> = 0 or 1.
ERROR Otherwise.
O - Return to On-Line Data Mode
This command specifies that the modem will enter the on-line data mode from the on-line
command mode with or without a retrain. If in the off-line command mode when this command
is entered, the modem reports ERROR.
Syntax
O[<value>]
Defined Values
<value> Decimal number corresponding to the selected option.
0 Enters on-line data mode from the on-line command mode without a retrain. Handling is
determined by the Call Establishment task. Generally, if a connection exists, this command
connects the DTE back to the remote modem after an escape (+++).
1 Performs a retrain then enters on-line data mode from the on-line command mode.
Result Codes
OK <value> = 0 or 1 and a connection exists.
ERROR Otherwise or no connection exists
L - Speaker Volume
This command sets the speaker volume control according to the parameter supplied.
Syntax
