In linked operation, all data received from one of the two interfaces are transmitted
from the other interface.
The linked operation is available only for the LJ71C24. It is not available for the
LJ71C24-R2.
POINT
When two interfaces are in linked operation, the transmission time for one
character becomes equal to the hardware gate off time of the L series.
