The force out-of-character-alignment bit (FOCA) controls the operation of the character
alignment circuit on a serial link. A transition from logic zero to logic one in this bit forces
the receiver to the out-of-character-alignment state where it will search for the transport
frame alignment character (K28.5). This bit must be manually set to logic zero before it can
be used again.
