Appendix F: Installing a Modem Under Linux

Introduction

This appendix explains how to install a modem on a computer operating under the

Red Hat Linux 6.2 operating system. Other versions of Red Hat and other Linux op-

erating systems should be similar. Briefly, in Linux, you do not need drivers for most

standard external modems and most internal ISA bus modems. Programs in Linux

commonly call upon the port, rather than the modem.

Installation

Connect the external modem to an available serial port.

Setup

This section describes how to make sure Linux can talk to the modem and be able to

dial up to the Internet. Linux can use different programs and desktops depending on

who made the Linux operating system and what version it is. The following proce-

dures use the most commonly installed components of Red Hat 6.2. More informa-

tion can be found in your Linux OS owner’s manual.
