Chapter 7 - Installing on Linux

This chapter 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 operating systems should be similar. With
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.

Standard Linux Serial Port Definitions

PC port Linux port
Com1 ttyS0
Com2 ttyS1
Com3 ttyS2
Com4 ttyS3

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 dial up to the Internet. Linux
uses different programs and desktops depending on the version. The following procedures use
commonly installed components of Red Hat 6.2. More information can be found in your Linux OS
owner's manual.

Using the Modem to Call the Internet
Linux allows different graphic user interfaces (GUI). In the following steps, we'll use the Gnome Desktop
GUI and assume that the Internet Service Provider (ISP) you are calling assigns you the Domain Name
Service (DNS) and Internet Protocol (IP) addresses. For more information on DNS or IP, see the Linux OS
owner's manual or contact your ISP.
On the Task Bar at the bottom of the LCD, select the Gnome Footprint.
