What You Need

Configuring Your

modem with Plug

The first time you start Windows 95/98 after you’ve installed the modem, Windows 95/98 will auto-detect your modem. Since Windows 95/98 supports Plug and Play, most installations are trouble-free.

You must power on your modem before you star t Windows 95/98, or Windows 95/98 will not recognize your modem.

You need Windows 95/98 with Dial-Up Networkin g installed t o configur e your modem for Windows 95/98.

Plug and Play mode allows Windows 95/98 to automatically detect your modem and determine which modem configuration fi le (called an INF file) to use.

Follow the steps below to install the INF file for Windows 95/98:

Power on your computer and start Windows 95/98. Your computer will

TCP/IP is the main protocol used to transfer data via the Internet. To use TCP/IP with Windows NT, you must connect to your ISP using a PPP or SLIP connection.

Each ISP has different requirements. Before using this chapter to configure Windows NT to acc ess your ISP, contact your ISP to de termine if they have special instructions for Windows NT users.

For you to Use this connection

Use a dial-up connection to connect over the Internet.

SLIP only allows you to connect using IP and does not allow for server assigned IP addresses or server assign name server addresses.

Use a dial-up connection to connect over the Internet.

PPP allows you to connect using IPX, TCP/IP, Netbeui, and other protocols. PPP is a more recent development than SLIP and has become the standard way of connecting to the Internet.

Serial Line Internet Protocol (SLIP)

Point-to-Point Protocol (PPP)

Before you use these procedures, contact your ISP to

Also, if you aren’t using AppleTalk® Remote Access (ARA), set AppleTalk to Inactive (in Chooser).

The modem initialization string should be

AT&F1&D0

For instructions about how to set up your Macintosh communications software package, see the software installation instructions that came with the software.

Accessing the Internet through an ISP requires the following software:

■

MacTCP or Open Transport (TCP/IP from the Control Panels menu),

which has probably already been installed on your Macintosh

■

SLIP or PPP dialing software

You can find public domain PPP dialers (such as MacPPP, FreePPP) on the Internet.

To enable the 230K DTE support for the Business Modem and 25 mhz Business Modem you first must install the Macintosh (230K) High Speed Script and then configure Open Transport PPP.
