Restrict or deny access to a serial port by specifying one or more users or groups.You can deny access to one or more users or groups by entering an exclamation point (!) before the user or group name.For example, to explicitly deny access to a user called “noadmin” and enable access only to a single user called “johnd” you would enter the following: Select an authentication type for the serial port from the pull-down list. The default is no authentication (Type=None).Note: Authentication type “None” is not a valid option when the serial port is configured for Power Management connection protocol. The system defaults to “Local” if no authentication type is selected. Configure the time for the serial port to return to idle state, if the user name is not typed in the terminal after the login banner is displayed. The default timeout value is 60 seconds.This field is available only when a Bidirectional Telnet protocol is selected from Ports > Physical Ports > General > Connection Protocol.
