(If the argument is omitted, 1 is set as the default value.)
[Reference Program]
Refer to Page 271, "On Com GoSub (ON Communication Go Subroutine)".
[Explanation]
(1) When Com On Off is executed, even if communications are attempted, the interrupt will not be gener-
ated.
(2) For information on communication line Nos., refer to the Page 274, "Open (Open)".
(3) After Com Stop is executed, even if communication is attempted, the interrupt will not be generated.
Note that the receiving data and the fact of the interrupt will be recorded, and be executed the next time
the line is reopened.
