The read-only Connected property is used to determine if
the control has connected to the remote host. A value of true
indicates that the connection has been established.
Note that the Connected property should not be used to
determine if an active dial-up networking connection has been
established by another application. The property will only return
True if the control has been used to establish the connection
itself, or if a connection is inherited by setting either the
AutoConnect or Handle properties. To determine if
there are any active dial-up networking connections, check the
value of the Connections property.
