This is on Port 29999. It uses plain TCP socket, plain-text protocol, which doesn't require a library unlike RTDE. We can just connect, send a text command followed by a newline, and get a text response back. Its the "operator panel" interface: power, brakes, load/play/stop programs, safety status.

Common commands:

CommandEffect
power onPowers the arm on
brake releaseReleases the joint brakes
load <program.urp>Loads a saved program
playRuns the loaded program
stopStops the running program
unlock protective stopRecovers from a protective stop
robotmodeReturns current state (e.g. RUNNING, IDLE)

Each command gets a one-line text reply, e.g. power onPowering on.
