I'm thinking along the same path, regarding reading of power-meters. And i noticed this thread.

After browsing documentation regaring IEC 1107 protocol I'm wondering, arn't you trying to enter programming mode with baudrate 300, in your example?

Just as a test I sent an Acknowledgement with the programming command 

06 30 30 31 0d 0a                                            .001 

If i understod the specs correctly the last digit after ack reads: 0- read, 1-program

what would happen if you try:
06 30 30 30 0d 0a                                            .000

Will you still get the password request?
