Correction: While the FX-3A stops the motor if START STOP UNIT with an
equivalent to "sg_start --stop", it does not work correctly anymore
after it. Certain commands after that will hang the firmware up;
notably those sent when sd_mod is probing the disk. I.e. FX-3A fails
not exactly as CX-1, but similarly.
