Expert Mode
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 2-62. 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 panty
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
2-62), 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 2-62), the user enters “D” following the
system prompt and then the data endpoint number. For example:
Command: D9,5553822
“Command:” on the above line is the default system prompt while in Expert Mode. The user
enters all data following the prompt.
