Description
Set country code
The command AT+GCI allows the customization of the modem for different countries.
As default, the modem is set to Europe (CTR21) with AT+GCI=FD. Currently, the mo-
dem is only authorized for this country profile.
Please find a detailed list of the countries that can be set in Chap. 15 "Country Codes".
Note: Please note that all country settings will result in ALL modem settings
being reset to the default settings (such as AT&F&W). Therefore, please
select a country profile first and adjust the settings afterwards.
Disconnect connection
The modem terminates the connection.
Declaration of the connection protocol speed (MNP 10)
AT*H determines the speed that is used to exchange the declarations during the
MNP10 connection setup before the modems enter the MNP 10 mode.
AT*H0 Connection setup takes place with the highest possible speed. (de-
fault)
Connection setup takes place with 1,200 bps
AT*H1
AT*H2 Connection setup takes place with 4800 bps
Identification
The modem sends an identification to the PC, according to the following parameter:
Product code
ATI0
ATI1 Previously calculated EEPROM checksum
ATI2 Calculation of the EEPROM checksum and comparison with the
previously calculated checksum stored in the EEPROM. OK for cor-
rect comparison.
ATI3 Number of firmware version in the EEPROM
ATI4 Modem version number
Country code parameter (Germany = 006/Europe = 253)
ATI5
ATI6 Version number and revision of "data pump"
Determine baud rate
The command AT+IPR switches the automatic baud rate detection on and off.
AT+IPR=0 Activates the automatic baud rate detection (default)
AT+IPR=<n> Sets the modem to the fixed baud rate n. The following baud rates
are supported: 300, 1,200, 2,400, 4,800, 9,600, 19,200, 38,400,
57,600 and 115,200.
The setting AT+IPR is not saved with AT&W , which means that in order to inactivate
auto bauding, the command AT+IPR must be sent to the modem every time it is
switched on.
