Changed test code to be enabled/disabled by sending space character " " to VCU. Defaults to off so to start up the accelerator ramp hit space.

Added two other commands to DMOC. These were challenge/response frames but seem to contain necessary stuff to make the DMOC work.

Send all 5 frames out one after the other instead of in groups and also use shared alive counter. This seems to be how the original VCU worked.
