MODEM 32144
Appendix B: Summary Setup
Summary Setup is an advanced
feature designed to allow exper-
ienced users to quickly change
option settings for any mode. Most
options can be viewed from and
changed using a single LCD screen.
Summary Setup is the fastest way to
selectively change multiple options;
however, because the Summary
Setup screens show numerical
codes with very little explanation,
this method of options selection is
recommended only for
experienced users.
Even though Summary Setup
offers these advantages, it is recom-
mended only for experienced users
because there is very little guidance
on the LCD screen to indicate
which option is being changed.
Changes made through Summary
Setup modify the active modem
configuration and are saved to
memory when you exit Summary
Setup.
B.1 Summary Setup LCD Screens
Summary Setup (SUMMARY) is
accessed from screen 6 of the
SETUP menu. From the
SUMMARY screen, choose SETUPS
to change options—but for Hayes
mode operation (only), choose AT
to change options for which there
are associated AT commands
(Table B-1).

If you select AT, the AT
PROFILES screen will be displayed.
When you select a Hayes mode
configuration profile (user profile)
from the AT PROFILES screen, the
MODEM displays a setup screen for
the selected profile. The selected
profile is used as the active
configuration and is also
designated as the default user
profile. Select 0 (pushbutton 1)
to select profile 0; select 1
(pushbutton 2) to select profile 1.
Pushbutton 3, with the AT
PROFILES screen displayed,
enables you to select the default
configuration profile: By pressing
pushbutton 3, you can toggle
(switch) between profile 0 or
profile 1 as the default—the effect
is the same as issuing the &Y
command (&Y0 or &Y1).
The SUMMARY screen includes
a four-digit checksum value to the
right of the word "SUMMARY."
This number will change if any of
the option settings are changed, so
it allows you to determine if any of
the modem's option settings have
been changed, although you
cannot determine from this
number which options have
been changed. After setting up
the MODEM, record this number
for possible later reference.
