3821Plus Modem Installation

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, AT 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 ªhead startº 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 Configure Branch in Chapter 3.
