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.

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