I'd be surprised if that would do it. The fiducial crossing latches the = MCP (sloppy description), and it then reads the clinometer. It isn't = explicitly atomic (I think; I'd have to check the code to be sure) but I = wouldn't expect network issues to cause a delay here. THis is all based on vague memories of the code, and if the mcp locked = up somewhere else then all bets are off R
