However, connecting a Hot Cable to the other port (port not selected) overrides this field setting and activates the connected port. Connecting a Hot Cable to one of the serial ports only allows console redirection when a Hot Cable is actually connected to Serial 1 or 2. Use the modified serial cable described in Chapter 3, under Hot (Serial) Cable.
