Connecting to your Dial-up ISP
First you need a working modem. A hardware modem, internal or
external, is probably the easiest way to go Some have had good luck
with usb modems,
USB Modem Support
. Win modems, which are the most common type, are a
little more tricky. For information on using a winmodem see
linmodems.org or
Linmodem-HOWTO.
Once you have a modem that works with linux you need to get it
to connect to your ISP, I like to use "wvdial" for
this.
To use wvdial you must first create a wvdial.conf file by issuing the
following command:
[root@linux]$ wvdialconf /etc/wvdial.conf
Wvdial will then look for a modem, and if one is found output something
similar to the following:
Scanning your serial ports for a modem.

ttyS1<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 S11=55 +FCLASS=0 -- OK
ttyS0<*1>: ATQ0 V1 E1 -- ATQ0 V1 E1 -- ATQ0 V1 E1 -- nothing.

Found a modem on /dev/ttyS1.
ttyS1: Speed 115200; init "ATQ0 V1 E1 S0=0 &C1 &D2 S11=55 +FCLASS=0"
If wvdial found a modem it will write the file
/etc/wvdial.conf. You must then edit this file with your favorite
text editor to put in your account information:
Phone = your ISP's dialup number
Username = your account user name
Password = Your account password
Here is what my "wvdial.conf" file looks like.
[Modem0]
Modem = /dev/ttyS2
Baud = 115200
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
Init3 = ATM0
FlowControl = CRTSCTS
[Dialer default]
Area Code = 419
Username = *******
Password = *******
Phone = 0000000
Stupid Mode = 1
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Inherits = Modem0
Once this is complete, in a terminal with root permission
issue the command:
[root@linux]$ wvdial
wvdial will dial your ISP and conect. You can then use your
web browser, ftp, or whatever. To disconect and hangup the phone line press
CTRL-C.
