The Interval property specifies the interval, in
milliseconds, at which the connection is monitored by the control.
The minimum value of 0 indicates that the control should not monitor
the connection.The maximum interval value is 65536 milliseconds,
which is slightly more than one minute. The default value is 1000,
which causes the control to check the connection status every
second.
Note that setting the property value to zero will prevent the
control from detecting certain conditions, such as a disconnected
telephone line or a modem that is turned off.
