Hi Bwired,
Yes i think i have to send /?! cr lf
The datasheet for this type of meter = EN 62056-21 protocol is the same as IEC1107
In the attachment a explanation of the protocol and how it works
You have to send the request and get a reply this will tell you the id for the meter and the baudrate for the datatransmision.
The next thing is to send a ACK with the requested baudrate and you receive all the data from the meter.
