Programming Example
If CIO 000002 turns ON while the RS-232C Port Send Ready Flag (A39205)
is ON, the number of bytes of reading results specified in the RS-232C Port
Reception Counter (A393) are read from the Code Reader connected to the
CPU Unit's built-in RS-232C port and stored starting from the upper byte of
D00100.
