To disconnect from the console port type <CTRL>\.
To exit the shell session type: exit
The U-router NGW allows multiple users that issue the ‘ngw-term.sh’ command to connect to the
console port of the attached enterprise router. However, when multiple users log in, they each share
the same console port. This means that commands typed by one user will be seen by all other users.
Also, the output from the enterprise router is shared with all connected users.
12.4.4 Console Access from Command Line:
minicom
When you require more control over the serial connection to the enterprise router you can use the
utility: minicom. This utility allows finer control of the communication parameters of the serial port,
such as setting the number of communication and parity bits as well as functionality to upload
software images over serial connections. However, it also presents the drawback that only one
minicom session is permitted. When one user is using the minicom utility other users can not use
minicom. Therefore, this feature is regarded as: advanced and minicom can only be executed as
root user.
To become root on the U-router NGW you need to issue the ‘su’ command. The su command
switches to the super user – or root user – when you execute it with no additional options. Sudo
runs a single command with root privileges. When you execute sudo command, the system prompts
you for your current user account's password before running command as the root user.
To become root, type: sudo su
To execute minicom and open the internal RS232 serial port type: minicom -D /dev/ttyS2
To exit minicom you have to press <CTRL-A> followed by X
