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.
