Managing Option Sets

The modem is pre-set with Option Set 1 as the active configuration.

• For asynchronous application protocols, build on Option Set 1

with any custom or site-specific parameter options

• For synchronous and leased-line application protocols, build on

Option Set 2 with any custom or site-specific parameter options

Select one of the following procedures to customize an option set. The

AT commands you need are listed in Table 3-1 and Table 3-2.

Selecting and Customizing Option Set 1

Manage an asynchronous modem configuration as follows.

Configuring a Modem for Async Operation

Step Stage

Issue the ATZ1 command

to load Option Set 1.

Optionally, set custom parameter options.

If you set any options in Step 2, issue the AT&W1 command to save

the configuration as Option Set 1. (Refer to Table 3-1.)

Issue the AT&Y1 command to make the modem use Option Set 1 at

subsequent power-ups. Option Set 1 is active.

You can set options and issue commands in either of these ways:

• By issuing AT commands through a communications application

• With Fast’RVu (see Chapter 4)

Fast’RVu is especially useful for copying configurations to multiple modems.
