Sms4Domino assumes the modem has been properly initialized. This is true for a Cinterion modem
that uses the factory default settings. However, when a modem is moved from some other project to
Sms4Domino it may be necessary to change some modem settings.
Changing the settings is done by sending AT commands to the modem. We prefer connecting the
modem directly to a serial port. Trying to connect the unknown modem to the serial-to-Lan convertor
and then trying to talk to the modem over the LAN is not recommended.
This document assumes you are using Putty for communicating with the modem.
Following steps will be executed
Establish communication with the modem. It may be necessary to guess the baud rate
Reset the modem to the factory defaults
Set the required modem parameters
Save the parameters to non volatile RAM. After each reboot of the modem these settings will
be loaded automatically into memory.
Verify the PIN code of the SIM card
Establish communication with the modem
Find in the office a computer with a COM (RS-232) port. Determine the identifier of the COM
port. In most cases this will be COM1. The Windows device manager lists all known ports
Connect the modem to the COM (RS-232) port using a quality RS-232 cable.
Launch the putty program
