is that the only command that causes that traceback error? Because it looks like you are auth'd into internal mode and it's ready for the commands. I can't see how that one command could cause a traceback and nothing else would.
all subsequent commands do not work, in external mode yes, in internal mode I managed to get to the point where it emits 3 beeps due to the incorrect sum. Using the ps3uart gui I managed to work the first time, and I got these errlogs, based on my experience with the 3034, it would be a BGA defect on the RSX, but I'm selling a 2120 there related to HDMI, but from what I've read, this error is also related to the lack of rsx communication with the correct hdmi c.i.? What I think?

before I forget that there is some command responsible for showing the current version of the system?
