The Modbus daemon also supports setting of some system parameters. For this task the '''Write holding register''' command is used. System related parameters and how to use them are described below. The register number specifies where to start writing the required values. All commands, except “Change APN”, accepts only one input parameter. For the APN the number of input registers may vary. The very first byte of APN command denotes a number of SIM card for which set the APN. This byte should be set to 1 (in order to change APN for SIM card number 1) or to 2 (in order to change APN for SIM card number 2).
