User can enable port authentication (see section 4.2.3.1. TCP Mode), then user should enter correct
user ID and password of each port when he tries to access the serial port.
The user ID and password for each serial port can be set using this menu. When user adds a new
user for serial port, he can also assign permissible serial ports to the user selectively, as shown on
