AT Command Reference Manual

ATZ - Reset from Voice Mode
This command works the same as in Data and Fax modes. In addition, the Z command resets all voice related parameters
to default states, forces the #BDR=0 condition (autobaud enabled), and forces the telephone line to be selected with the
handset on-hook. No voice parameters are stored in NVRAM so the profile loaded does not affect the voice aspects of this
command. (Note that when #CLS=8, ATZ causes a hang up if the telephone line is connected.)
Parameters: Same as Data and Fax modes.
Result Codes: Same as Data and Fax modes.
#BDR - Select Baud Rate (Turn off Autobaud)
This command forces the modem to select a specific DTE/modem baud rate without further speed sensing on the interface.
When a valid #BDR=n command is entered, the OK result code is sent at the current assumed speed. After the OK has
been sent, the modem switches to the speed indicated by the #BDR=n command it has just received.
When in Online Voice Command Mode and the #BDR setting is nonzero (no autobaud selected), the modem supports a full
duplex DTE interface. This means that the DTE can enter commands at any time, even if the modem is in the process of
sending a shielded code indicating DTMF detection to the DTE. [Note that when #BDR has been set nonzero, the modem
employs the S30 Disconnect Inactivity timer, and this timer starts at the point where #BDR is set nonzero. If this period
expires (nominally 60 seconds) with no activity on the DTE interface, the modem reverts to #BDR=0, #CLS=0, and #VLS=0.]
Parameters: n = 0 – 48 (New baud rate is n*2400 bps)
Default: 0
Result Codes:
OK For the supported speeds.
ERROR Otherwise.
Command options:
#BDR? Returns the current setting of the #BDR command as an ASCII decimal value in result code
format.
#BDR=? Returns a message indicating the speeds that are supported.
#BDR=0 Enables autobaud detection on the DTE interface.
#BDR=n Where 1<n<48. Sends OK message at current speed, then switches to the new speed defined by
n*2400 bps unless and until another #BDR=n command is received. Autobaud is disabled, and
the character format is maintained at the format most recently detected.
#CID - Enable Caller ID Detection and Select Reporting Format
This command selects or disables Caller ID recognition and reporting in any mode.
Parameters: n = 0, 1, or 2
Default: 0
Result Codes:
OK n = 0, 1, or 2.
ERROR Otherwise.
Command options:
#CID? Returns the current setting (0,1 or 2) of the #CID command as an ASCII decimal value in result
code format.
#CID=? Returns the message, “0, 1, 2”.
#CID=0 Disables Caller ID.
#CID=1 Enables formatted Caller ID reporting of ICLID SDM (Single Data Message) and
MDM (Multiple Data Message) packets.
