    Assuming some sort of energy metering project.

    What modem specifically are you using? Can you provide links to description or documentation?

    Would imagine USART, SPI or I2C would be normative modes of connectivity.

    A modem - any modem - is simply device which connects a 'host' (or 'DTE') to some communications link.

    https://en.wikipedia.org/wiki/Modem

    Details of how the modem interacts with its 'host' will be in the modem's documentation.

    So: have you studiedthis modem'sdocumentation?

    As

    Turvey.Clive.002

    ‌ said, UART/USART, SPI, I2C would be common ways for a modem to

    interact with its 'host'. Again, this will be detailed

    in the modem's

    documentation.

    A common protocol for

    a modem to

    interact with its 'host' overUART/USART is to use so-called AT Commands:

    https://en.wikipedia.org/wiki/Hayes_command_set

    And, again,

    this will be detailed

    in the modem's

    documentation.

    euridis modem is going to be realized by me and I find difficulty in the design part of this modem that will realize the communication between energy meter and PC

    So are you familiar with the basics of how any modem interacts with its 'host' ?

    Surely, that would be the place to start ...

    Are we talking about this: 

    http://www.euridis.org/

     ?

    And, thus, about this: 

    https://en.wikipedia.org/wiki/IEC_62056

     ?

    But, presumably, not this: 

    https://www.euridis-ecole.com/

      ?
