For the Belgian digital meter, you need the Sagemcom T210-D version.

First try with putty:

In order for putty to use the serial port, you have to run it as root, or add yourself to the dialout group.

sudo usermod -a -G dialout marc

logout and login, and check if you are in the dialout group

id marc

uid=1000(marc) gid=1000(marc) groups=1000(marc),4(adm),20(dialout),24(cdrom),27(sudo),30(dip),46(plugdev),116(lpadmin),125(sambashare),127(wireshark),133(libvirt)
