Install Communications
Software
A computer commands and controls a modem through
communications software. This software uses the AT
command set to send instructions to the modem. A dumb
asynchronous terminal, however, does not require this
software since it can directly send AT commands.
The 3821Plus can be used with any major
communications software. Refer to your software's user's
guide for installation procedures. For an overview of how
to use AT commands and a list of AT commands
supported by the 3821Plus, refer to Chapter 4,
Commands and S-Registers.
Select Factory Configuration
Options
After the modem passes the power-up self-test,
configure it for operation using one of the factory preset
configurations.
The 3821Plus modem has several factory preset
templates that contain the most commonly used
configuration options (straps) for
Asynchronous Dial (shown as Async Dial on the
SDCP)
Synchronous Dial (Sync Dial)
Synchronous Leased (Sync Leased, Answer or
Originate mode)
UNIX hardware network (UNIX Dial)
If ETC is installed:
Cellular mobile (Cellular(Mobile))
Cellular PSTN (Cellular(PSTN))
Your modem is shipped from the factory with the
Async Dial default configuration options stored in
memory. If Sync Dial, Sync Leased, UNIX Dial, or
Cellular is more appropriate for your configuration, then
you must change the factory setting using either the SDCP
or the AT command set as described in the following
sections.

The preset configuration gives you a "head start" in
getting your modem operating and reduces the amount of
time required to configure your modem. For a better
understanding of SDCP operation and factory preset
configuration options, refer to
Chapter 3.
