MODEM 32144
Synchronous modes 1, 2, and 3:
A change in DTR (ON or OFF)
which lasts for less than the value
in register S25 (in 1/100ths of a
second) is ignored by the modem.
S26—RTS TO CTS DELAY
INTERVAL. This register affects
synchronous operation only. With
the command &R0 in effect, CTS is
turned on in response to an OFF-
to-ON transition of RTS from the
local DTE—after the delay
specified by the value in register
S26 (but only if the modem is on-
line and ready to receive
synchronous data).
5.6 Saving Option Selections
Changes made to option settings
will cease to be effective if power is
removed from the modem or if a
factory reset has occurred—unless
the modem configuration (all
option settings) is saved to
nonvolatile memory. The storable
parameters of the modem’s
configuration can be saved to user
profile 0 or 1 using the &W
command (&W0 or &W1). Upon
powerup, the modem will recall
either profile 0 or profile 1,
depending on which has been
designated as the default profile.
(The modem is shipped from the
factory with profile 0 as the default
profile.)
As explained in the following
sections, the modem is
programmed to treat profile 0 and
profile 1 differently. Use profile 0
for your standard configuration
and make it the default profile
(&Y0). Profile 1 (optional) is
intended to be used to store an
alternate configuration (e.g., for
an alternate application).
To view the contents of the
user profiles, use the &V and \S
commands.
User Profile 0
User profile 0 is linked to the
modem’s front panel (i.e.,
selections made using the front-
panel LCD).
• If you make option changes
using the front panel, the
changes for options for which
there are associated Hayes
commands will be saved to
profile 0 when you exit the
SETUP menu.
• If profile 0 is recalled as the
active configuration, the LCD
screens will reflect the profile 0
configuration.
• If profile 0 is changed by means
of Hayes commands or via the
Summary Setup feature and
then saved, the changes made
will be reflected on the LCD
and will be effective for all
modes.
If you make option changes from
the front panel but have not exited
the SETUP menu, and then make
option changes using Hayes
