from http://social.msdn.microsoft.com/Forums/en-US/roboticssimulation/thread/13fb26c8-75fe-43b9-9e65-6a915e7d2560 :
In RDS 2008 there is some discussion of the Generic Differential Drive in the Help file.
AllStop should cause the current operation to be cancelled, as you expect.
It will then disable the drive and you will have to issue an EnableDrive request before you can get the robot to move again.
This is by design so that AllStop can act as an Emergency Stop and prevent any further action without an explicit reset.
There should be a notification from the drive service that the drive power has been set to zero after the AllStop.
