All computers that communicate on the Internet speak one common language. Each system exchanges data using TCP/IP. TCP (Transmission Control Protocol) is just one way that a computer can send data to another system to share its data. IP (Internet Protocol) extends the use of TCP to include systems on the Internet. Together TCP and IP make for a unified way to exchange the email, web pages, and software archives that we all love to use the Internet for.

Apple's Remote Access Software (a.k.a. OT/PPP) extends the capability of TCP/IP to modem operation, using the PPP control panel System 8.1 (Point to Point Protocol) or Remote Access (ARA). This software makes your modem connect to a network, even though you are calling over a telephone line. This is how most users access the internet.

In addition to using your modem to connect to other computers or networks, you can use it to give yourself or others remote access to your computer.

When another user is connected, they can access shared files as if you were both connected to the same local network. The same file and user access privileges apply.

To enable dial-in access:

1. If necessary, set up your modem.
2. Open the Remote Access control panel.
3. Open the RemoteAccess menu and choose Answering.
4. Select the Answer Calls option.
   

To provide dial-in access for a specific user (recommended):

1. Open the File Sharing control panel and click the Users & Groups tab.
2. Select the user and click Open.
3. Open the Show pop-up menu and choose Remote Access.
4. Select "Allow user to dial in to this computer."

If your computer is also connected to a local network,
you can grant a dial-in user access to the network:

• Open the Remote Access control panel
• open the RemoteAccess menu
• choose the Answering command
• then select "Allow access to entire network."
