MultiModemBA User Guide

1.1 Introduction

Welcome to the world of data communications. You have acquired one of the finest intelligent

desktop data/fax modems available today, the MultiModemII BA series modem, from Multi-Tech

Systems. This User Guide covers various models within the BA series, and unless otherwise noted,

all content should be considered relevant to all models.

Your MultiModem provides data communication at the following rates:

33,600 - 14,400 bps (Enhanced V.34 / V.32bis)

The MultiModem also provides other prevalent data communications standards and includes dial

backup with automatic lease line restoration, adaptive protocol enhancing used in typical Unix® batch

file transfers and support for IBM's AS/400TM and WindowsTM environments.

1.2 How To Use This Manual

The information contained in each chapter and appendix is as follows:

This chapter begins with a short introduction, followed by a guide (which you are now reading) to the

use of this manual. There is a discussion about what components you can expect in your modem

package. We then provide a more detailed description of the modem, including the modem’s

technical specifications. Chapter 1 includes sections covering power, LED indicators and a brief

summary of PC board controls. (Chapter 9 covers switch settings more thoroughly.)

Chapter 2 covers the procedure for connecting the modem to your computer and to the phone line.

Details are given, supported by illustrations on the modem's back panel connections as a guide to

install your modem to the point of operation. In addition, this chapter describes the installation of

PhoneTools, the communications software included with your modem.

Chapter 3 documents communication software configuration recommended specifically for the

MultiModem. Other issues covered include setting up initialization strings, changing default

parameters, configuring software for the remote system and file transfer protocols.

Chapter 4 may be the most important chapter of this manual. It begins with an introduction and

discussion on Command Mode fundamentals. A flow chart is provided to illustrate Command Mode

and On-Line Mode operation and the methods used in each mode. Next, there is a summary of the

modem’s commands and responses. We then go into a detailed explanation of each modem

command, providing examples where applicable.

Chapter 5 covers the modem's S-Registers, which enable the user to establish, read, and modify

various modem options. All of the S-Registers are charted and explained, followed by instructions on

accessing the S-Registers and reading or changing their values.
