If the input condition turns ON when the Protocol Macro Executing Flag
(CIO 191915 for port 2) is OFF and the Communications Port Enabled
Flag (A20207 for internal logic port, communications port 7) is ON, com-
munications sequence No. 100 registered in the Serial Communications
Board is called, and data is sent and received via port 2 of the Serial Com-
munications Board.
The amount of send data depends on the number of words specified in
D00000 (the number of words after D00001 plus 1 for D00000 itself), and
is sent from the next word after D00001.
Number of words
S:D00000

The receive data is stored in consecutive words beginning with D00011,
and the number of words actually stored in D00010 (the number of words
after D00011 plus 1 for D00010 itself) is stored.
