VMware supports the use of removable devices (such as USB devices and DVDs) with the guest operating system (ATDE). Depending on the device, these devices cannot be used simultaneously by the host operating system (the operating system running VMware) and the guest operating system. In order to use such a device in the guest operating system, it must be connected to the guest operating system.

	For details on how to use removable devices, please refer to the documentation for the VMware software you are using on the VMware site (http://www.vmware.com/).

In order to perform the operational checks of Armadillo-IoT, the devices shown in 表3.2「Removable Devices Used for Operational Checks」 must be connected to the guest operating system.

In ATDE, we start a command line terminal that provides a CUI (Character-based User Interface) environment. Various commands to be run on ATDE are input and executed with the command line terminal. While there are several types of command line terminals, here we start the GNOME terminal installed by default in the GNOME desktop environment.

To start the GNOME terminal, please enter terminal from the activityin the upper left of the desktop like 図3.1「Starting the GNOME Terminal」 and select Terminal.

図3.1 Starting the GNOME Terminal

A window opens as shown in 図3.2「GNOME Terminal Window」.

Set the serial communication settings of the serial communication software (minicom) as shown in 表3.3「Serial Communication Configuration」. Also, please set the width of the terminal used to start minicom to 80 or more characters. The display may become disordered when entering commands if the width is less than 80 characters.

To start minicom configuration, please do as shown in 図3.3「Configuring minicom」. After configuration is completed, save it to the default setting (dfl) and exit.

[PC ~]$ LANG=C minicom --setup

To start minicom, please do as shown in図3.4「Starting minicom」.

[PC ~]$ LANG=C minicom --wrap --device /dev/ttyUSB0

	Depending on the environment, the device file name may differ from that in the examples in this document and for example may be /dev/ttyS0 or /dev/ttyUSB1.

To quit minicom, first enter Ctrl+a followed by the q key. After that, when the following is displayed, move the cursor to "Yes" and press Enter to quit minicom.

                                   +-----------------------+
                                   | Leave without reset?  |
                                   |     Yes       No      |
                                   +-----------------------+

	Enter Ctrl+a followed by the z key to display minicom's command help.

To start vi, enter the following command.

[PC ~]# vi [file]

When the path of the filename is specified with file, the file will be edited (and the file will be created if file does not exist). vi starts in the command mode state.

To enter characters, it is necessary to switch from command mode to input mode. To make this switch, enter the command shown in 表3.5「Commands to Enter Input Mode」. After entering input mode, characters are input as-is when their key is pressed.

To return from the input mode to the command mode, press the ESC key. If you ever lose track of the current mode, just press the ESC key and return to the command mode once to avoid confusion.

	Turning Off Japanese Conversion Functionality
	When entering a vi command please turn off the ATDE Japanese input system (Mozc). Turning the Japanese input system on and off can be done with half-width / full-width key.

The starting position of character input when the "i" and "a" commands are entered is shown in 図3.10「Explanation of Commands for Switching to Input Mode」.

	Delete Characters in vi
	Depending on the environment of the console, characters may not be deleted when using the BS (Backspace) key, with the "^ H" characters entered instead. In this case, delete characters using the command described in 「Deleting Characters」.

The cursor can be moved with the arrow keys, but it is also possible to move the cursor by entering the commands shown in 表3.6「Commands to Move the Cursor」 in command mode.

To delete a character, enter the command shown in 表3.7「Commands to Delete Characters」 in command mode.

The characters deleted when the "x" and "dd" commands are entered are shown in 図3.11「Explanation of Commands for Deleting Characters」.

図3.11 Explanation of Commands for Deleting Characters

The commands for saving the file and quitting are shown in表3.8「Commands for Saving and Quitting」.

Commands for saving and quitting start with ":" (colon). When entering the ":" key the cursor will move to the bottom of the screen and the entered command will be displayed. After entering the command, press Enter to execute the command.
