You need to ask meter to start using 9600. It's configured that default is 300. You can also try to change start baud rate.
If you start with IEC and want to use DLMS you ask meter to move IEC mode E. That is binary mode and DLMS uses that. You don't need to do any readout if you want to use DLMS. You can try with GXDLMSDirector and see how that is doing it.
