FYI, I use these states in the driver, shown here with the corresponding message in the plugin: ACM_IDLE (no message since it's doing nothing) ACM_WEST, ACM_EAST "Dish target %d, position %d" ACM_REACHED "Position reached" ACM_STOPPED, ACM_CHANGE "Motor wait" ACM_ERROR "Motor error" Limit control is not done by the driver but by the plugin, and the messages are "Dish at limits" (in manual mode) "Position outside limits" (in positioning mode) There's also a "Position not set" if the new channel is in it's in a source that's not been memorized (I'm currently implementing a cStatus to detect channel switch).
