In data measurement, a byte is the equivalent of one character (a letter, a number, a punctuation mark, etc.) and is made up of 8 bits of data. See also "Megabyte".



Call Waiting
If you have call waiting, it could potentially interrupt your modem connection. Unless you are expecting a very important phone call while trying to use your modem, it's probably best to have call waiting disabled. You can do so either through the Dialing Properties in the modem Control Panel or by customizing your init string. Common AT commands to disable call waiting include *70, 70#, and 1170. See also "init string" and "AT Commands".

COM Port
A communications port is a serial port on a computer. Data traveling through a serial port will be transferred single file, one bit at a time (i.e. in a series). Serial ports are rather like a two-lane highway. Data can only travel one bit (one car) at a time in one direction. The following is a list of available COM Ports and their default resources:

COM Port Port
COM 1 03F8 4
COM 2 02F8 3
COM 3 03E8 4
COM 4 02E8 3

As you can see, COM1 and COM3 share an IRQ as do COM2 and COM4. Most systems have the mouse configured to COM1, the modem to COM2, and do not have any devices assigned to COM3 and COM4. With this configuration, the mouse and modem can work together without conflicts. However, if devices are added to COM3 and COM4, it may be advantageous to manually configure their IRQs in order to avoid conflicts with COM1 and COM2.
This is the command interpreter for MS-DOS, and it is one of the necessary start-up files on a PC system.

A gamepad is one example of a digital control device, while most joysticks are analog control devices.

A DOS table that contains file information such as name, size, time, and date of last modification, and the cluster number of the file's beginning location.

Direct Serial Connection
See "Null Modem".

DirectX (DX)
The DirectX is an Application Program Interface (API) platform developed by Microsoft which provides an environment that allows developers to use a standardized format when programming a game, thus making it accessible to a wide variety of different hardware features. Prior to DirectX, developers were forced to write hardware-specific code (with a specific driver for each different piece of hardware). DirectX is a library provided by Microsoft to sit in the operating system and provide game programmers with seamless access to all of the hardware features available today. The DirectX library is divided into 5 main sections: DirectDraw, Direct3D, DirectSound, DirectInput, and DirectPlay. These include:

DirectPlay: This is the multiplayer gaming module in DirectX which provides seamless access to networking functionality for gaming. DirectPlay supports direct serial connections, modem play, LAN play and Internet Play. DirectPlay also supports third-party on-line gaming services by allowing them to develop their own DirectPlay drivers for use with games that support DirectPlay.

Direct3D: Sits on top of DirectDraw and provides access to hardware 3D acceleration if it is available. Direct3D is designed to work with the full range of 3D cards on the market, giving a smooth interface to your 3D hardware. Using Direct3D with your 3D accelerator can provide tremendous speed improvements as well as better image quality at higher resolutions.

DirectInput: Provides a means for the programmer to make use of the large variety of input devices on the market - from mice, keyboards and joysticks to gamepads and beyond. It also allows programmers to use some of the later advanced features in some hardware.

DirectSound: Provides access to the audio hardware on the system, allowing for the full features of the audio hardware to be used (such as 3D sound). As with the other components, DirectSound is a seamless way to write directly to your sound hardware.

DirectDraw: Provides access to video hardware for 2D graphics, allowing the use of the full range of resolutions and color depths provided by modern hardware. DirectDraw also improves performance of some 2D graphics functions by allowing video acceleration in hardware.

Since DirectX is relatively new in the computer world, we have found that some older systems may contain hardware that may not be fully DirectX compatible. If you are unsure whether or not your system will support DirectX, please contact the manufacturer of your system for more information.

Popular operating systems include MS-DOS, Mac OS, Windows and UNIX. The term DOS is often used to refer specifically to Microsoft’s MS-DOS, since it is the most common disk operating system.

DOS Compatibility Mode
DOS compatibility mode is a function that occurs in Windows 95 when the hardware is only using 16-bit DOS drivers to control one or more aspects to your computer. There are several things that can cause DOS Compatibility Mode:

  1. You are using 16-bit drivers that do not permit Windows 95 to use its 32-bit drivers to control a piece of hardware.
  2. The piece of hardware in question was not recognized by Windows 95 or any of its default drivers and hardware specific drivers may not have been loaded for that particular device.
  3. You are using an older motherboard that does not have the ability to run 32-bit applications thus forcing Windows 95 to run ALL drives in DOS compatibility mode.
  4. Your CD-ROM drive is being controlled through a sound card's IDE (Integrated Device Electronics) interface. When configured this way, Windows 95 will not detect that there is a CD-ROM drive present and will not install drivers for it.

For updated 32-bit Windows 95 drivers contact either the computer or the hardware manufacturer for the device in question.

DOS Extender
A program that allows a DOS application to use a flat 32-bit memory model so it can easily access memory above the 1 MB limit for better performance and ease of configuration (as opposed to loading an Extended Memory Manager). Protected Mode programs use a DOS Extender to manage the memory as one large block. See also "Protected Mode" and "DOS4GW.EXE".

The most common DOS Extender (made by Rational Systems, Inc.), which is used to manage memory as one large block with DOS applications that run in Protected Mode. See also "DOS Extender" and "Protected Mode".

DOS Mixer
A utility that is provided by the sound card manufacturer to control the volume levels in Dos. The Mixer in Windows is a separate utility that does not effect the sound in Dos.

File Allocation Table (FAT)
A DOS table at the beginning of a disk that tracks where files are stored on the disk according to the file allocation units used by the files.

File Compression
In order to make downloading files easier, a lot of files are compressed. This makes them smaller and easier to download (taking up less time). Depending on the compression method, you may need a utility (such as PKUNZIP or WINZIP) to decompress the file. Some files may be self-extracting. Check out Manufactures Links for more information on how to obtain PKUNZIP or WinZip.

An Internet standard that provides for the transfer of files from one computer to another. FTP can be used at a command prompt, or with a GUI interface, which is available with FTP software or with a Web browser. When using a Web browser, enter the command "ftp" in the browser URL line instead of the usual "http://" used to locate a Web site. LucasArts maintains an FTP site where demos and patches may be accessed by the public at "".



Game Card
We commonly recommend disabling the I/O port and enabling the joystick port on the sound card. The joystick port on the sound card is a good alternative to I/O card based joystick ports. The best possible joystick port is typically present on dedicated and/or speed adjustable game cards, which is a relatively inexpensive expansion card designed specifically for use as a dedicated game port.

General Protection Fault (GPF)

Your link to the Internet.

HTML (HyperText Markup Language)
Hypertext Markup Language is used for writing pages for the World Wide Web. HTML allows text to include codes that define fonts, layout, embedded graphics, and hypertext links. Hypertext provides a method for presenting text, images, sound, and videos that are linked together in a non-sequential web of associations. The hypertext format allows the user to browse through topics in any order. There are tools and protocols that help you explore the Internet. These tools help you locate and transport resources between computers.

HTTP (HyperText Transport Protocol)
The common transfer protocol used by Internet browsers on the World Wide Web.

A hub is a component that provides a common connection among computers in a network. It is the central component in some server-based networks. A hub allows computers of different types to all communicate together. Most hubs are active in that they regenerate and retransmit signals. This type of hub is referred to as an "active hub" and it requires electrical power to run. A "passive hub" can be a wiring panel or punch-down block. Passive hubs simply organize the wiring. They do not amplify or regenerate the signal. The signal passes through the passive hub. Passive hubs do not require electrical power to run. A "hybrid hub" is one that will accommodate several different types of cables. Usually these include one main hub connected to several secondary hubs that then connect to computers. A break in any of the cables attached to a hub affects only that segment. The rest of the network keeps functioning. See also "Server-Based Network".

You can use some Windows tools, such as the modem control panel, to test your modem. (Note: Not all systems have this utility installed. If your system does not, test the modem using the other two methods or consult your Windows documentation on installing HyperTerminal).

  1. From the Windows 95 Start Menu, select Programs -> Accessories -> HyperTerminal
  2. Double Click on the Hypertrm icon (sometimes called Hypertrm.exe)
  3. Under the Named field, type in the word time and then click OK
  4. In the phone number field, type in 767-1111. This is the public service number to check the correct time of day and should be valid in most area codes.
  5. In the next window, click on Dial. This will bring up a display of the status of your connection as the modem attempts to dial. You should hear a recorded message stating the correct time if the connection is successful.
  6. After the connection sequence has finished, exit the HyperTerminal window.
  7. When prompted to save the session, reply "NO".

See also "Modem Control Panel" and "Dial-up Networking".

Init String
Also referred to as AT commands. An init string (initialization string) is a series of commands used to instruct the modem to perform certain tasks, such as "dial", "hang up", "use software flow control", and so on. Some modem manufacturers design special features into their models. Customized init string commands are provided in order to take advantage of these features. The modem's documentation will specify the recommended commands for the init string. See also "AT Commands" and "Command Set".

This port is typically used to connect a Joystick to a computer. An I/O Port (a.k.a. Joystick port) can be active without the presence of a port on the back of a computer. The common places to disable a I/O Port are on the systemboard or controller card, usually it requires moving a DIP switch/jumper to a disabled position to correct joystick port conflicts with sound cards and/or dedicated game cards. In some cases, the I/O Port can be controlled by the system BIOS. We recommend contacting the manufacturer for further information on how to disable the I/O Port on your computer.

IP (Internet Protocol)
The main protocol used on the Internet.

IP Configuration Viewer
This utility (included with Windows 95) allows you to view your TCP/IP settings, such as your IP address. To join an Internet game, you will need to know the IP Address of the computer hosting the game. The host can use WINIPCFG.EXE to identify the IP address and give this number to you so that you can find their game on the Internet.

IP (Internet Protocol) Address
A 32-bit "dotted decimal" address consisting of four numbers separated by periods used to uniquely identify a device on a network that uses TCP/IP protocols. The first numbers identify the network, the last number identifies the host. An example of an IP address is See IP Configuration Viewer for information on how to obtain your IP address.

This is a four part number that is your particular identification number for your computer on the Internet. However, you or your computer are not referred to by this number, but rather by the name you may use. Every machine that is on the Internet has a unique IP number - if a machine does not have an IP number, it is not really on the Internet. Most machines also have one or more Domain Names that are easier for people to remember.

LAN (Local Area Network)
When two or more computers are linked via a network cable, usually in a limited geographical area, such as the same floor in a building or in the same company, they are referred to as being on a Local Area Network.

This term is a measure of the amount of time that it takes for data to travel from one computer to another over a network or the Internet. This lag time can be measured using the PING command. See the Useful Utilities section for more information on the PING command and latency. Latency is usually not an issue on a Local Area Network, but on the Internet, excessive latency can cause game performance to degrade substantially. Therefore, when playing any game over the Internet, it is important to have a low latency connection. High latencies can cause poor multiplayer performance and can decrease stability.

Consists of two or more computers connected to each other by a cable so that they can share data. A group of computers and other devices connected together is also referred to as a network, and the concept of connected computers sharing resources is called networking. One advantage of networking is that it is much cheaper to share resources, such as a printer, rather than installing a printer at every computer on the network. It's also faster to send and receive files via a network than it is to copy one document from a floppy disk onto every system that needs to use it and then have to recopy & redistribute the document each time it's modified.

A computer that uses an Intel (or compatible) processor and can run DOS and Windows.

Peer-to-Peer Network
One of the two basic types of networks. In a peer-to-peer network, there is no dedicated server or hierarchy among the computers. All the computers are equal and therefore are known as peers. Normally, each computer functions as both a client and a server, and there is no one assigned to be an administrator responsible for the entire network. The user at each computer determines what data on their computer gets shared on the network. See also "Server-based Network".

Peripheral Component Interconnect (PCI)

This is a DOS command-line program (included with Windows 95) that allows you to measure latency between your computer and another computer on a TCP/IP network or the Internet. It sends a small amount of data to an IP Address you specify and awaits a response. When it gets a response from the other computer, it will display (in milliseconds) how long it takes for the data to make the trip over the network. This is called "pinging" the host.

Protected Mode
Protected Mode utilizes all the available RAM to run a program. Protected Mode programs use a DOS Extender to manage the memory as one large block. The most common DOS Extender is DOS4GW (DOS4GW.EXE). Memory managers are not required or recommended for use with Protected Mode programs. Memory managers (i.e., HIMEM.SYS, EMM386.EXE, and QEMM) can decrease performance or crash a protected mode program. In our experience, we have found that 500K of free conventional memory is necessary to allow the Dos Extender (DOS4GW.EXE) to launch so that it can manage the memory for the game.

Many PC applications that were produced before the introduction of extended memory make use of expanded memory. One of the most common third party memory manager programs available that enables applications to use extended memory as though it were expanded memory is QEMM by Quarterdeck. However, we have had reports of our games experiencing problems with this device driver, so we recommend the use of EMM386.EXE to allocate extended memory as expanded memory for use with our games which require expanded memory, such as "X-Wing Collector’s CD-ROM." See also "HIMEM.SYS," "Expanded Memory (EMS)," and "Extended Memory (XMS)".



Random Access Memory (RAM)
Temporary memory stored on chips or modules such as SIMMS or DIMMS inside the computer. Information in RAM disappears when the computer's power is turned off.

Read Only Memory (ROM)
Chips that contain programming code and cannot be erased.

Real Mode
Allows Intel processors to emulate the 8088 chip found in the original IBM PC. One of the many limitations of running in real mode is that the program must fit entirely into a computer’s lower 640K of memory (conventional memory). Also, if a real mode program requires device drivers and/or TSR’s to be loaded (i.e. sound card, mouse, CD-ROM, etc.), there is usually not enough free conventional memory for everything to fit into the 640K area and still have enough left over for the program to run. Therefore, it is necessary to load device drivers and TSR’s into upper memory using a memory manager such as EMM386.

A small section of code in the network operating system that intercepts requests in the computer and determines if they should be left alone or redirected out to the network. This allows computers attached to a network to work as stand-alone systems as well as allowing for the remote access of data via the network.

A fast way to access an application is to run a short-cut to the application. Windows allows for the creation of short-cuts to applications that can be placed on the desktop for easy access. On a Macintosh system, a short-cut is referred to as an "alias."

Signal Bounce
Because the data is sent to the entire network, it will travel from one end of the cable to the other and continue uninterrupted if it isn't either received by a computer or terminated. This is referred to as signal bounce. The presence of this continuous signal bouncing back and forth over the network prevents any other computer on the network from sending a signal at the same time. See also "Terminator".

SIMM (Single In-Line Memory Modules)
Miniature circuit boards that are used in newer computers in place of traditional RAM chips. These mini-boards hold 8, 16, or 32 MB on a single module.

Synchronous Transmission
Synchronous communication relies on a timing scheme coordinated between two devices to separate groups of bits and transmit them in blocks known as frames. In synchronous transmissions, the digital pulses are coordinated by the system clock of either computer. Start and stop bits are not required since the bits are sent and received in a timed, controlled matter. Transmission simply stops at the end of one frame and starts again with a new one. If there is an error, the data is retransmitted.

System Administrator
A person in charge of a host machine or network.

System BIOS
Basic input/output system chip(s) residing on the systemboard that control(s) normal I/O to such areas as system memory and video display.

Terminate-and-Stay-Resident Program (TSR)
A program that is loaded into memory but is not immediately executed, such as a screen saver or a memory-resident anti-virus program.

To stop a network signal from bouncing, a component called a small terminator device is placed at each end of the cable to absorb free signals. Absorbing the signal clears the cable so that other computers can send data. Every cable end must be plugged into something such as a computer or cable extender. Any open cables must be terminated to prevent signal bounce. See also "Signal Bounce"

UART (Universal Asynchronous Receiver Transmitter) Chip
Helps to convert parallel data from the computer into a serial data stream for transmission over a phone line (i.e. modem) and accepts serial data from the modem and converts it back into parallel data for the CPU. UART's also have a character buffer to store extra characters that the CPU doesn't have time to process immediately. The buffer sizes on earlier UART's were only able to store one character. Data characters which were stored in them would often get over-written by in-coming characters if the CPU was too busy to process them in time. The 16550 UART has a 16 character FIFO buffer and performs flow control. This decreases the number of character over-runs. It is recommended to enable the FIFO Buffer setting if the modem has a 16550 UART. See also "FIFO Buffers".

A driver that is used to initialize a video card for high resolution. UniVBE is good, but we recommend using the VESA (high resolution) driver from the manufacturer of the video card, this driver takes advantage of the video card's built-in features for high resolution.
