Configuring Serial Ports [OSD]
T To Configure Who Can Access Serial Ports
[OSD]
After selecting a serial port, an administrative user can use the options on the
“Port permissions” screen to grant or deny access by users or groups to a
selected serial port or to all serial ports. By default, all users can access all
serial ports. Adding a user or group to the port access list has the following
effects:
• The user or group is granted access to the port unless the additional step is
taken to deny access.
• All other users are denied access to the port, even “root” and “admin.”
