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 operating 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.

Connect the external modem to an available serial port.

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 procedures use the most commonly installed components
