On the Access screen under Configuration>Serial/AUX>Physical Ports in Expert mode, an administrative user can perform the tasks shown in the following table.
Restrict access to a serial port by specifying one or more users or groups (and thereby excluding all others) or by denying access to one or more users or groups
The default is all users have access. See “To Configure User Access for One or More Serial Ports [Expert]” on page 200
Choose an authentication type for the serial port from the following pull-down list.
 
The default is no authentication (authentication type=None). See OnSite Authentication Options, if needed for more details. For the procedure, see “To Configure an Authentication Method for Logins Through a Serial Port [Expert]” on page 201.
Access can be denied 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 “manuel,” you would enter the following:
!noadmin,manuel
