EXPERT MODE (V2)

Description

Expert Mode is an enhancement to the Command Mode feature that provides an alternative method of performing the full range of Command Mode functions. By eliminating the display of menus and allowing multiple commands to be entered on a single line, Expert Mode lends itself to computer-driven instructions. Individual users who are very familiar with Command Mode operations may also find it useful.

When	Expert	Mode is activated, a system administrable prompt is displayed that can consist
of up	to nine	characters (the quote character and RETURN are not allowed). Command: is
the system default prompt.			As with dialing in Command Mode, the	ASCII characters
backspace (BS or CTRL-H)			or underscore (_) may be used to cancel a	previously entered

character. When in Expert Mode, each line must be terminated with a keyboard RETURN.

Users of Expert Mode must follow the exact tree structure of Command Mode (both up and down the menu tree) as shown in Figure 2-51.However, instead of moving one level at a time, Expert Mode allows the user to move up or down several menu levels at once. This can be accomplished by entering, on a single command line, the capitalized letters that define the sequence of menu selections desired. For example, to change data port parity from the tree’s entry level, the user types OCPE and presses RETURN. This requests that parity be set to “even”, but does NOT enable the change. To enable this change (see Figure 2-51),the user must now type XE and press RETURN.

Activating Expert Mode

A user can move back and forth between Command Mode and Expert Mode by typing “!” (exclamation mark). For ports on a Data Line circuit pack (Data Line Card, DLC), either Command Mode or Expert Mode is presented at the start of a new session, depending upon the port’s setting at the termination of the previous session. Thus, if a data session ends in Expert Mode, the next session will begin in Expert Mode. However, calls from an AT&T STARLAN NETWORK to System 25 will always begin a new session in Command Mode.

An alternative command, “>”, can be used to guarantee entry into Expert Mode. Conversely, guaranteed entry into Command Mode can be accomplished with the command “>!” followed by RETURN. These commands are especially useful for computer-driven DLC endpoints that might otherwise have difficulty detecting whether a new session had been started in Expert Mode or Command Mode.

Making a Data Call

To make a data call from the entry level (see Figure 2-51),the user enters “D” following the system prompt and then the data endpoint number. For example:

Command: D9,5553822

Note: “Command:” on the above line is the default system prompt while in Expert Mode. The user enters all data following the prompt.
