During the battery swap at tower this morning, power apparently was cycled to the power mote. This seems to have caused it to reverted to Wisard output, but the xml assumes it is serial. I first tried mp=2, which I believe is what we use for the sensor motes, but this apparently outputs uncalibrated data. After flailing for a while, I finally came up with mp=1, which is back to calibrated serial data. Finally, apparently, eeupdate doesn't work for power motes, so I expect it to lose this setting again if power is cycled.
