I have two laptops, one running 1.2.56 and one running 1.2.53. On the .56 one, whenever I try to go into CLI with either of my copters, the CLI just spits up random characters. I tried both copters on .53, and they can both CLI fine. Both copters can connect over USB and 3DR for telemetry, but they can't connect to 1.2.56 for CLI. Thought I'd report this, I'll just use .53 to download my logs for now.
