I should also add that the motors set to 1M baud seem totally unresponsive now, even when communicating with a microcontroller. So it seems I bricked another motor by apply what seems like a harmless setting from the UI. Please help!

One more update. I issued the command 3E 14 01 00 53 to a motor and got the response: {3E}{14}{01}{38}{8B}{00}{04}{04}{00}{00}{00}{50}{FF}{46}{00}{14}{00}{64}{64}{64}{00}{1E}{08}{00}{00}{00}{00}{52}{03}{00}{00}{00}{00}{80}{FC}{0A}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{00}{78}{56}{AA}{55}{FF}{FF}{FF}{FF}{A7} Problem is, now the motor is completely unresponsive. The LED is flashing constantly, even after a power cycle. What did I do wrong?
