NON-Tango: “UPD_MOT: INCONSISTENT_ACCU” after Ctrl-C

Pressing Ctrl-C may lead to inconsistent register contents. Software and hardware disagree. The problem is fixed by:

 
do stop_all_moves()
* = cmr()

If cmr() find disagreements, you are prompted, whether you want to fix it. Say “yes” then chose the hardware to be correct.
