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).

To view which countries are available in the modems firmware, enter AT+GCI=?<CR>.

The modem will display all of the possible two digit country codes available.
