What to Select in the Communications Software Package’s Modem Menu List

1) Select Codex 3260 Modem, Motorola 3260 Modem, or another 3260 option

from the package’s modem list. Packages that directly support the 326X Series
Modem support industry-standard commands and Motorola-enhanced
commands, making further configuration unnecessary.

2) If a 3260 option does not appear in the list, contact the software manufacturer

for the latest version of the package (which should have such an option).

3) Select a Hayes-Compatible entry. With this option, Motorola-enhanced

commands (AT

*

) are not supported.

4) Try operating the communications software. If you have problems, refer to the

“Operating Notes” section, next, and to Chapter 6, Troubleshooting Guide.

Operating Notes

Keep the following in mind when using the modem with communications software.

General Notes

The information in this section applies to all 326X Series Modem platforms.

Selecting an Option Set

Option Set 1 was designed for use with asynchronous communications software
packages. It is compatible with most communications software. Option Sets 2, 3, and
4 are intended for different applications and have different default settings. Select
Option Set 1 when using a communications software package.

Establishing a Connection with Option Set 1

With Option Set 1, the modem operates as follows:

1) The modem attempts to establish a LAPM connection.

2) If the connection is unsuccessful, the modem attempts to establish an MNP

connection.

3) If the previous connections are unsuccessful, the modem attempts a Normal

mode connection to the remote modem. All data that is sent to the modem’s
attached computer terminal before the modem establishes a connection is lost.

Auto Dialing and Answering in Option Set 1

When the modem is configured for Option Set 1, and the communications software
package executes an auto dialing and answering operation, the modem automatically
adjusts its baud rate to the communications software baud rate and parity. This rate
remains constant during the established connection.
