5. In the Path field, enter /tmp/<socket> or another Unix socket name of your choice. 7. Select The other end is a virtual machine.
8. By default, the device status setting is Connect at power on. You may deselect this setting if you wish.
Click Advanced if you want to configure this serial port to use polled mode. This option is of interest primarily to developers who are using debugging tools that communicate over a serial connection. For more information, see Special Configuration Options for Advanced Users.
9. Click Finish, then click OK to save your configuration and close the virtual machine settings editor.
