Note:
-
The connection information setting area should be specified before open processing is carried out (the
request signal goes on).
-
Changes to the connection information setting area are invalid while the open complete signal is on. To
change the contents of the area, first close the connection, and then carry out re-open processing after
the changes have been made.
-
The open request signal should be kept on until close processing is carried out.
