What is PPP?
Point-to-point Protocol (PPP) is a method for connecting a personal
computer to PittNet and the Internet using a standard phone line and a
modem. The difference between PPP and other, older dial-up procedures
is that a PPP setup will establish a direct Internet connection that
allows the
PC to use
TCP/IP (Internet-based) applications as if it had
its own direct
Internet port instead of just a phone jack. Communication programs
such as Telnet, FTP and PopMail, as well as Gopher and Netscape, will
all run from a
Windows-based PC with
a good PPP connection. The University of Pittsburgh offers PPP
communication to its computing community through all available dial-up
lines.
In
order to make a connection using PPP, you must have a modem capable of
at least 14,400 bps communication. A slower modem may be successful,
but the performance may be too slow to be of any practical use.
You
do not need to install a communications package such as Trumpet
Winsock or LAN WorkPlace in order to initiate PPP communication using
a modem on a Windows 98 PC.
Do
not install the "PittSLIP" package currently being distributed via the
CIS computing lab file servers or any other outside communications
package on your Windows 98 PC as they may severely impede your
machine's communications ability.
If you have a PC with an
older version of Windows (Windows 95 or earlier) then these directions
do not apply to your PC setup. See the CIS help sheets
Dialing into PittNet on Your Windows
(3.1) PC Using Trumpet Winsock Software,
Dialing into PittNet Using PPP
on your Windows 95 PC, or
Dialing into PittNet on Your
Windows NT 4.0 PC.
Fortunately for users of Windows 98, no additional software is needed
in order to set up PPP communication using a modem. However, your PC
must be instructed to use Internet protocols, including PPP.
Getting Your Modem Installed
-
To see if your PC
can recognize your modem, click on the "Control Panel" folder icon,
available under "My Computer." In the Control Panel window, click on
the "Modems" icon.
-
If Windows 98
detects a modem, then the modem will be listed on the Modem's
window.
If this appears, then
you can skip ahead to the section titled
Installing Dial-up
Networking.
-
If Windows 98 does
not detect a modem, then you will be prompted to go through the
installation process. If you have not physically installed the
modem, turn off your machine and install the modem card. Then,
restart your PC to see if the modem is recognized by plug-and-play.
The "Install New
Modem" screen that appears will give you options for installing either
a PC Card (PCMCIA) modem or an internal or external modem Both the PC
Card modem and the external modem installation process use "wizard"
screens that will take you through the installation as a series of
steps, represented by different screens.
Modem
Installation Tips
-
After the install
process has been initiated by the wizard program, it will attempt to
automatically recognize your modem again. Click the "Yes" button
when the wizard program asks you if you wish it to attempt to locate
the modem automatically.
-
The "wizard"
procedures have been set up intelligently enough so that if you
follow along with the suggested or default settings, you should have
few problems.
-
The wizard
installation program will try to set the modem up on your PC's COM1
communications port. Some PCs will require that Windows 98 install
both the port and the modem at the same time. If this is not
possible, then the wizard program will install just the port using
the "Add New Hardware" wizard program. If this happens, follow the
"New Hardware" process to the end and then click "Finish." Then
restart your PC and click on the "Modems" icon again to start a
separate process for the modem installation.
-
Some internal
modems on Windows 98 PCs cannot be recognized properly due to
conflicts with certain sound cards. If your PC is not correctly
recognizing your internal modem, try removing the sound card and
restarting the PC. With this possible conflict temporarily
eliminated, the PC may be able to recognize the modem properly and
the sound card can then be re-installed and the PC started again
with all equipment recognized and functioning.
-
If you are using an
external modem on an older PC, you should make sure that the
COM port that the modem will be using has a "16550 UART" chip
controlling it. Check your PCs specifications or use the MSD program
(if you have installed this program) in "DOS Prompt" mode to check
your PCs COM ports. If necessary, you may have to reconfigure the
COM port that your modem uses or attempt to use a port controlled by
an older 8250 UART chip. PC Cards (PCMCIA modems) will have this
chip built in.
Installing
Dial-up Networking
NOTE: You
should follow the directions in this section only if you DO NOT see a
folder icon for "Dial-up Networking" after you double-click on the
icon for "My Computer."
If this icon
does appear,
than you can skip ahead to the section entitled
Configuring Your Dial-Up Networking for the Pitt Environment.
To Install Dial-up
Networking Components:
-
Double-click on the
"Add/Remove Programs" icon in the "Control Panel" folder.
-
Click on the tab
icon for "Windows Setup" so that the "Windows Setup" section is
prominent.
-
Highlight the
"Communications" line by clicking the mouse once on the line and
then clicking the "Details" button on the lower part of the screen.
1 . The "Communications" window will appear
Make
sure that the box next to "Dial-up" Networking" is checked. This can
be done by positioning the arrow-shaped pointer onto the box and
clicking the left mouse button once so that a check mark appears.
-
Click on the "OK"
button on the "Communications" window and then click the "OK" button
in the lower section of the "Add/Remove Programs Properties" screen.
Windows 98 will
install the necessary communication components from files stored on
the hard disk, or it may prompt you for the Windows 98 installation
disks or CD.
-
Next, double click
on the "Network" icon located in the "Control Panel" folder.
-
The "Network" window appears. If the "Configuration" section of the
window is not prominent, click on the tab icon for "Configuration."
1 .This section lists various communications components that must be
installed in order to establish network and PPP communication. The
first of these that you must check for is the Dial-up adapter. If a
line and icon for "Dial-Up Adapter" is present, skip to the next
section
1 .
If such a line is not visible, click on the "Add" button.
2 . A dialog box will appear entitled "Select Network Component Type."
Use the down arrow key to highlight "Adapter" and then click on the
"Add" button.
-
The "Select Network
Adapters" window will appear with two different sections. Double
click on the "Microsoft" line in the Manufacturer's box on the left,
and then on the "Dial-Up Adapter" line. The icon should appear in
the section on the right, under the "Network Adapters" line.
Click
on the "Dial-Up Adapter" line once so that it is highlighted and click
the "OK" button.
