Table C-1 Continued Command Sn? T Vn Xn Z +++ Description Read an S Register. ATSn? reports the value of the register designated by "n," which may be the number of any valid S register. Parameters: none Range: n = 0 - 27, 29, 31 - 33, 35, 37, 89 NOTE: Values are reported in decimal format. To interpret bit-mapped register values, convert the decimal value to binary. Tone Dial. ATT sets the dialing mode to Tone. Tone dialing is the default mode. This command can also be used as a dial modifier. Parameters: none Result Code Form Option. ATVn determines the type of result code returned from the modem. Parameters: n = 0, 1 n = 0 Result code is sent as numbers (short form or digits) n = 1 Result code is sent as text (long form or verbose) (default) Result Code Set/Call Progress Option. ATXn selects the result code set and dialing functions. The Vn command determines if the result code is sent as words or numbers. Parameters: n = 0 - 4 n = 0 CONNECT result codes are enabled. CONNECT XXXX result codes are disabled. Busy signal and dial tone are not detected. n = 1 The modem blind dials: CONNECT XXXX result codes are enabled. Busy signal and dial tone are not detected. n = 2 The modem waits for dial tone before dialing. CONNECT XXXX result codes are enabled. Busy signal is not detected. n = 3 The modem blind dials: CONNECT XXXX result codes are enabled. The modem sends BUSY result code if busy signal is detected. n = 4 The modem waits for dial tone before dialing. CONNECT XXXX result codes are enabled. The modem sends BUSY result code if busy signal is detected (default). Reset Command Option. ATZ instructs the modem to go on-hook and restore the profile saved by the last &W command. Escape Code Sequence. When the character set in register S2 is sent to the modem three times in rapid succession (see S12), the modem escapes to the command state. The default value for the escape character is +. When instructed to enter +++, enter the character set in register S2 three times in rapid succession. Do not precede the escape code sequence with AT, and do not press the Enter key afterward. NOTE: To return to the online state, use the ATO command. C-4 Modem Commands

by "n," which may be the number of any valid S register.
Parameters: none
Range: n = 0 - 27, 29, 31 - 33, 35, 37, 89
NOTE:
Values are reported in decimal format. To interpret bit-mapped
register values, convert the decimal value to binary.
T
Tone Dial. ATT sets the dialing mode to Tone. Tone dialing is the
default mode.
This command can also be used as a dial modifier.
Parameters: none
Vn
Result Code Form Option. ATVn determines the type of result code
returned from the modem.
Parameters: n = 0, 1
n = 0
Result code is sent as numbers (short form or digits)
n = 1
Result code is sent as text (long form or verbose) (default)
Xn
Result Code Set/Call Progress Option. ATXn selects the result code set
and dialing functions. The Vn command determines if the result code is
sent as words or numbers.
Parameters: n = 0 - 4
n = 0
CONNECT result codes are enabled. CONNECT XXXX result
codes are disabled. Busy signal and dial tone are not detected.
n = 1
The modem blind dials: CONNECT XXXX result codes are
enabled. Busy signal and dial tone are not detected.
n = 2
The modem waits for dial tone before dialing. CONNECT XXXX
result codes are enabled. Busy signal is not detected.
n = 3
The modem blind dials: CONNECT XXXX result codes are
enabled. The modem sends BUSY result code if busy signal is
detected.
n = 4
The modem waits for dial tone before dialing. CONNECT XXXX
result codes are enabled. The modem sends BUSY result code if busy
signal is detected (default).
Z
Reset Command Option. ATZ instructs the modem to go on-hook and

to the modem three times in rapid succession (see S12), the modem
escapes to the command state. The default value for the escape
character is +. When instructed to enter +++, enter the character set in
register S2 three times in rapid succession. Do not precede the escape
