• Hit the ENTER key to engage the vxWorks prompt. The prompt should appear. If the prompt does not appear, then the box is hung beyond a capability to soft-reboot, requiring a hardware reset.

• If the prompt appears (usual case), then hold down the control button and enter the character x. Then release both keys. This key combination will invoke a soft reboot. The terminal output will scroll display text as the boot progresses.
• Alternatively, you could type "reboot" at the prompt and enter to get the vxworks vme crate to reboot.

• After the boot completion, press CONTROL and ] simultaneously. This will escape the vxWorks prompt and replace it with a "telnet>" prompt. Type the word quit. This releases the terminal session.
