Appendix D – Installing a Modem 

under Linux 

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.

an

 

available

 

serial

 

port.

  

Setup

 

This

 

section

 

describes

 

how

 

to

 

make

 

sure

 

Linux

 

can

 

talk

 

to

 

the

 

modem

 

and

 

be

 

able

 

to

 

dial

 

up

 

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
