When Command Mode is enabled, the Command Line Interface (CLI) is attached to the Serial Line. Command Mode can be enabled in a number of ways:

The Always choice immediately enables Command Mode for the Serial Line.

The Use Serial String choice enables Command Mode when the Serial String is read on the Serial Line during boot time.

The Wait Time specifies the amount of time to wait during boot time for the Serial String. This timer starts right after the Signon Message has been sent on the Serial Line.

The Serial String is a string of bytes that must be read on the Serial Line during boot time in order to enable Command Mode. It may contain a time element to specify a required delay in milliseconds x, formed as {x}.

The Signon Message is a string of bytes that is sent on the Serial Line during boot time.

Place a binary character into either the Serial String or the Signon Message using [x]. For example, use decimal [12] or hex [0xc].
