Sleep mode operation
The modem can be set to enter the low power sleep mode by setting ATS24=n . In this case, “n” is
time, in seconds, that the modem will operate in normal mode with no detected telephone line or
DTE line activity before entering low power sleep mode. The timer is reset upon any DTE or
telephone line activity. If S24 is set to zero, the modem will never enter the low power sleep mode.
Disconnecting a call
There are several ways to disconnect a call. Below are the choices.
Resetting the modem’s power or toggling the Reset Line (Pin #12) will disconnect and put the
modem back into the OFF line state.
An ON to OFF transition of the DTR signal (Pin #4) will also disconnect the modem. If you use this
method, check to make sure that the DTR command is set to &D2 or &D3 and not forced (&D0).
The remote device can also cause the modem to disconnect. If the remote modem disconnects
your modem will automatically sense the loss of the carrier signal and return to the OFF line state.
The ATH or ATZ commands can also be used to disconnect a call. In order to issue a command to
the modem when it is On Line, the modem must be placed into the On Line Command State . This is
accomplished by issuing a special escape sequence. The default value of this three digit escape
sequence is the “+” character (see S2 to change). The “+++” is protected by a one-second delay
before and after it is sent (see S12 to change the time) When the modem detects the escape
sequence, the OK result Result code will be displayed and the modem is in the On Line Command
State . The ATH or ATZ command can now be issued to disconnect the call.
Selecting country codes
Setting the modem’s country code is done by with the +GCI command. To change to one of the 30
available countries, issue the AT+GCI=n command where “n” is one of the two digit country codes.
This command must be issued each the modem is turned on. It will not automatically store or save
this setting. It should be part of the Initialization string.
Example: AT+GCI=00<CR> Meaning: Change country code to Japan.
OK Meaning: The modem has accepted the command and is
now configured to operate in Japan
AT+GCI?<CR> Meaning: Display current country code
+GCI:00 Meaning: (Japan is the current country selected).
