_{1. Introduction}

_{1.1 What is TCP/IP Access to a network computer?}

_{TCP/IP provides "network-level" access via telephone-and-modem from your home computer to a network computer and to the worldwide Internet. With TCP/IP access, you are able to use the same microcomputer client software that you might use on a computer with a direct (Ethernet) connection to a network computer: Telnet, Netscape, Microsoft Internet Explorer, FTP, POPmail programs such as Eudora, Netscape Mail, Microsoft Internet Mail, Microsoft Exchange Mail, and so on.}

_{By comparison, conventional telephone-and-modem access to a network computer and the Internet involves using a simpler communications program, HyperTerminal for example, so that your computer can emulate a terminal. This enables you to log into a large host computer where you may be able to use Telnet, Lynx, FTP, and E-mail, but only with the host-provided interface.}

_{When connected via TCP/IP, your computer temporarily becomes a part of a network computer. The home computer uses a modem, and only relatively small quantities of data can be moved quickly across its link. Hence, some common Internet activities (such as downloading large files or accessing and displaying remote graphics files) may proceed slowly.}

_{1.2 Obtaining an Account and Other Requirements}

_{In order to use TCP/IP, you must obtain a network computer TCP/IP Account from an internet provider. Look in your local yellow pages, under Internet or Computers for available internet providers.}

_{The network computer TCP/IP Account is a special kind of account which permits you to dial into a special modem pool at your internet provider and access the network with TCP/IP-based software. It is not an account on a computer you log into and use for e-mail or other communications purposes. To have an e-mail account, you must subscribe to another online provider or the same internet provider as your TCP/IP account, but you must also request and probably pay for the e-mail account.}

_{To summarize:}

_{a network computer TCP/IP Account- permits network-level TCP/IP access}

_{to a network computer}

_{Most network providers support the following IBM-type PC hardware/software configuration for TCP/IP access to a network computer:}

_{* IBM-type PC running Microsoft Windows 3.x and Windows 95}

_{* 10 megabytes or more of free hard disk space}

_{* High-density floppy disk drive}

_{* Trumpet Winsock TCP/IP software running on Windows}

_{* Any error-correcting modem. A 9600/14400 bps or 28.8+ Kbps modem}

_{is strongly advised. To support speeds greater than 14400 bps, a}

_{modem should support the V.34 high-speed modem standard.}

_{To use your new TCP/IP account with Windows 95 you must have both your modem and Dial-up Networking properly installed and configured. To configure your modem check the on-line help for Windows 95 or the manual for your modem. Please note that after you complete some of these steps Windows 95 may suggest that you restart your computer. Follow the instructions that Windows 95 recommends and then continue configuring Dial-Up Networking where you left off. To configure Dial-Up Networking please read all of the following information. If you already have dial up networking installed skip to section 3.}

_{This document describes requirements and installation procedures for using Microsoft Windows 95 for remote access to a network computer.}

_{Many other hardware and software configurations in addition to those listed above are possible, and a wide variety of commercial software packages supporting TCP/IP access are available.}

_{1.3 What Phone Number Do I Call?}

_{The phone number of the network computer TCP/IP modem pool is given to you when you subscribe to your internet provider. This is the number you call to connect to the network computer and the internet.}

_{2. Installation}

_{2.1 Software Requirements}

_{* Microsoft Windows 95 with Dial up networking installed}

_{* TCP/IP software, e.g. Netscape, Microsoft Internet Explorer}

_{2.2 Hardware Requirements}

_{4. Solving Problems}

_{The most common problems with TCP/IP dial-in and Microsoft Windows}

_{result from either a modem that has not been configured to use}

_{"hardware" (RTS/CTS) flow-control or from an attempt to communicate}

_{at a speed beyond the capabilities of Windows and the particular PC}

_{being used.}

_{4.1 Modem Hardware Flow-Control}

_{Most new modems shipped today are configured at the factory for}

_{"hardware" flow control; many older modems were not. If you}

_{experience communication problems - especially the symptom of}

_{successful initial dial-in connection but lack of success when}

_{running an application like Netscape or Microsoft Internet Explorer}

_{or Telnet - the safest course of action is to explicitly configure}

_{your modem for hardware flow control.}

_{4.2 Attempting 28.8+ Kbps Communications}

_{Successful communications at 28.8+ Kbps is highly dependent upon}

_{telephone line quality; not all line characteristics affecting data}

_{communications are audible to the human ear. Connection quality can}

_{vary widely according to your location or time-of-day, or even the}

_{weather. As a result, connections can be "flaky", especially if}

_{the quality of the phone connection is just on the border of being}

_{adequate for full-speed 28.8+ Kbps communications. Sometimes}

_{things work better if you lower your connection speed to 19.2 Kbps.}
