Being a huge nerd I simply had to try connecting in to my SRc via serial. I haven't had any luck finding a command reference from Lectro but I've been able to get it talking to my mac over USB, and I've figured out the serial equivalents of most of the menu items. I'll attach what I've found so far. The things I can't yet get to happen are IR sync, scanning, and smart tune.
Some or all of this may be wrong, this is just an afternoon's hacking project. Feel free to correct me where needed.
