AccuMark Data Communication Tools Working Process

AccuMark Data Communication Tools Requirements

AccuMark Data Communication Tools Requirements

The AccuMark DataComm Tools package includes the following items:

• DataComm Tools User's Guide

• System Requirements

In order for the software to work, as a minimum you must have the following items:

• AccuMark system running Release 7.6.2 or higher

• Modem

• Other Reference Guides

Before using this program, you should have a working knowledge of the AccuMark, Hewlett-Packard workstation, and modems. If questions come up in any of these areas, refer to specific product documentation.

Purpose of the Program

The AccuMark DataComm Tool allows transfer of data between computer systems connected by modem or over a Local Area Network (LAN) or Wide Area Network (WAN).

• The data transfer performs several functions: • Makes the connection between local and remote AccuMark computers

• Displays types of data available and their storage location

• Copies selected data from the source location to the new storage location

When sending — data is sent from your computer to another computer.

When receiving — data is retrieved from a computer and stored in your computer.

There are three major functions associated with this software: • Setup provides the software with information about each remote user.

This allows the systems to communicate with each other.

• Initialize set parameters on the modem.

• Data Transfer transfers data.

The System Administrator can perform all functions, but any user with system access can transfer data. All functions are available through the AccuMark Explorer.

Remote Access of Computers

LAN connections require TCP/IP.

WAN connections require PPP on Windows NT/95/98, or SLIP protocol on UNIX systems.

Upon establishing connection with the remote computer (Windows or UNIX) the user can:

• Authenticate himself/herself

• View disks, storage areas and AccuMark data items on remote site

• Copy or move data items between computers

The AccuMark Explorer detects the presence of TCP/IP network and RAS software. If one of the components is missing, the new features based on it become unavailable.

For proper installation of TCP/IP and RAS, consult with appropriate operating system’s manual, or Microsoft Windows online help. A compatible modem must be installed and configured for dial-up connections.

Technical Overview

The software consists of two parts: AccuMark Explorer (client) and AccuMark Server (server), which communicate through sockets.

The AccuMark Explorer uses Microsoft Foundation Class (MFC) implementation of sockets, while the server uses direct sockets API, provided by Windows 95/98/NT and UNIX operating systems.

Port 3072 is used for socket communication and it is configurable (for timeout and number of connection attempts).

The built-in RAS API is used for dial-up connection in Windows NT/95/98. Scripts and ppl commands are used to establish the SLIP connection on UNIX. Since Windows NT/95/98 does not support SLIP RAS Service, and the current version (10.x) of HP-UX does not support PPP protocol, it is impossible to establish a dialup WAN connection from a UNIX implementation of AccuMark Explorer to Windows NT/95/NT computers. This is the only limitation, which will be removed once the new version (11.x) of HP-UX is used.

LAN Overview

Using the AccuMark DataComm Tool, any active servers will automatically be represented in the connected computer list of Remote Computers. (The DataComm Tool on the local computer will poll the network to identify active servers.)

If a new computer is connected after the Remote Computer icon is expanded it will not display automatically. Use the Refresh feature to display it.

Some computers on the LAN may not display. The network administrator should have the names of these computers.

WAN Overview

Using the AccuMark DataComm Tool, active WAN servers can be represented in the connected computer list of Remote Computers.

If a new computer is connected after the Remote Computer icon is expanded, it will not display automatically. Use the Refresh feature to display it.

Some computers on the WAN may not display. The System Administrator should maintain the names of these computers.

There are four things needed to ensure that data transfer over a WAN works smoothly. These are:

1. A remote user account on the computer you are communicating with. This allows access to the server.

2. An individual computer user account on the computer you are communicating with. This allows access to AccuMark files.

3. Remote site and user information for each computer such as:

• SLIP name and address

• Host name

• Remote user account name and password

• Phone number

4. A modem, configured and initialized for your system.

Server Administration

When the DataComm tool is first installed, the appropriate servers must be identified. Users will only be able to communicate with the configured servers.

In addition to the configuration information required by DataComm Tools, the administrator must set up proper account information to enable users to log onto the server. Refer to appropriate NT online help or documentation to set up user profiles.
Windows95 and NT Environment

1. Open the Control Panel or System Services.

2. Select the AccuMark Service icon to see this screen:

Initially the fields are blank, indicating that no server is configured.

3. Select the New Server icon to configure a server. This will bring the following screen to fulfill. The Logging and Status tabs offer optional functionality, with defaults as indicated in these illustrations.

The Comment line can be used to provide additional identification of the server: for example, “Marketing Server.” This information will appear in the description field of the AccuMark Explorer when the server is displayed.

Logging will record the connections made to the server. Designate the log file storage location in the Base Path field.

The default Status configuration indicates the server status (yes/no) in AccuMark Explorer.
AccuMark Data Communication Tools Working Process

To Establish New LAN Connection

A remote computer may be installed on a LAN (Local Area Network) or WAN (Wide Area Network). When creating a new LAN connection, this dialog box will appear:
To Establish New LAN Connection

1. Highlight the Remote Computers folder item, in the left pane of AccuMark Explorer.

2. Select File/New/New Computers... from the main menu. A dialog box will appear.

3. Enter the data into the dialog box fields.

• Computer Name - name or IP address of the remote computer.

For Windows 95/98/NT (not on UNIX) implementation of AccuMark Explorer you can look up a remote computer’s name on the LAN by clicking the Browse… button. The Browse for Computer dialog will appear. Some LAN servers will appear in the drop down list.

• Comments – description of the computer (optional). This field contains information that was entered in the Server Configuration field when the server was configured. It can be used to help identify the computer to the user, and appears in the description column of the AccuMark Explorer window.

To Establish New WAN Connection (Dialup computer)

A remote computer may be installed on a LAN (Local Area Network) or WAN (Wide Area Network). When creating a new WAN connection, this dialog box will appear:
To Establish New WAN Connection (Dialup computer)

1. If the new remote computer will be on a dial-up phone line, the Dial-up connection box has to be checked.

2. For dial-up computer, the Connection list box will contain all available entries for RAS dial-up connections. You can create new entries, delete obsolete entries and modify properties of selected entry by clicking New…, Delete, or Property… buttons.

• If the new computer on a dial-up network runs the UNIX operating system (HP-UX) , the Connect to UNIX computer box has to be checked, and the Dial-up host name field has to be filled.

Dial-up host name is the SLIP name or IP address of the local computer. The IP address should be unique within the network and usually start with 10.0 prefix. The last digit must be an odd number.

NOTE: If the new connection is to a UNIX computer, click in the Connect to UNIX Computer checkbox. When this checkbox is selected, the Dial-up Host Name field becomes active also.

UNIX Connection

Before transferring data, your computer must know certain things about the remote computer that it communicates with. Usually, this information is entered right after the software is loaded. Over a period of time, this information may need updating or remote sites added or deleted from your files. The remote computer information needed is:

• SLIP name

• SLIP address

• Host name

• Login name and password of the remote user account

• Phone number

The SLIP name and address are similar, but not exactly the same as the host name and IP address.

If your hostname is “CUSTOMER” your SLIP name might be “SLIPCUST1.”

If your IP address is “,” your SLIP address might be “”


The user is required to authenticate himself/herself to AccuMark server. A password provides this authentication.

For dial-up computers the extra authentication for RAS sub-system is needed, so that the dial-up connection can be established. The authentication is only relevant for UNIX and Windows NT.

Windows NT will use the authentication to access network drives.

Windows 95/98 has no security context. On Windows 95/98, AccuMark Explorer uses the security context of currently logged on user (logged to the remote computer).

NOTE: An assigned password can be saved (when Remote Login screen is first filled). This allows the user to sign in without re-entering the password.

User Interface


Remote Computers - On the left pane of the AccuMark Explorer’s main window. To add new computers, highlight this item and select File/New Computer… from the AccuMark menu.

Connected computer - If there are any active servers on LAN, the computer on which that server resides will be represented by this icon. If the computer with an active server running is added to the LAN after expanding the remote computers’ folder, the folder will not be updated automatically. You must use the Refresh command (F5) to update the computer list.

Disconnected computer - Represents System Administrator-defined items which are not currently connected.

Note that only computers on Microsoft or NetWare Network will be displayed. Some remote computers on LAN or WAN with TCP/IP connection, UNIX computers and computers on dial-up network will not be shown in the browser dialog. To obtain the name for those computers, contact the System Administrator in your organization.

Storage on Remote Computers

Storage areas on a remote computer are located under a remote computer’s icon, as displayed in the AccuMark Explorer. For UNIX remote computers, the storage areas will display according to the user’s authentication. The user shall see only areas for which he has been authorized.

The storage area window has the following headings:

Name – storage area name

Type – remote storage area


Drag and drop – to use the mouse/pointer to select and move a file icon to another location, where the mouse button is released; this causes the file to be copied to the new location

Initialize - Preparing a device to be put into use. A modem needs to be initialize so it knows the settings that allow it to communicate (send or receive) with other computers.

IP - Internet Protocol

LAN - A Local Area Network (LAN) is made up of two or more computers connected by communications cables. Often LANs are used within work environments to share data and printers or plotters.

Local - Your computer
