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.

'euridis modem ' for remote communication between an energy meter and a concentrator (stm32 ...)

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.

Are we talking about this: 

http://www.euridis.org/

 ?

And, thus, about this: 

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

 ?

But, presumably, not this:

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 ...
