Overview

About dataComet: dataComet allows Macintosh computers to access remote services on the Internet using the Telnet protocol. This protocol allows your computer to interact with a remote host as if it were a terminal directly attached to that host. Using the Internet's Telnet utility, however, requires that you know which host you want to log onto. In most instances, you will probably obtain the name of the host or its IP address from an Internet resource, from a book, or from some other published source. (Each host has an IP address. IP addresses uniquely identify each computer on the network.)

dataComet allows you to save your Telnet connections as icons to your desktop. Then, each time you want to connect to a particular host, you can double-click its saved Telnet icon. This is a quick way to start a session with those remote hosts that you want to connect to regularly. For directions on how to save a Telnet session, see "Saving a Telnet configuration."

Note: Network software is upgraded frequently. These instructions are for dataComet 4.6. The version you are using may work somewhat differently.

Documentation: For information about where to get the dataComet software, see the ISC-Supported Products document on dataComet.

For more information about dataComet configuration, commands, and features, refer to the vendor's documentation.

Establishing a connection to a remote host

To establish a connection to a remote host:

  1. Double-click the dataComet icon to start the application.
  2. Select "New" from the File menu. Type the name of the session, as you want to remember it, in the Window name field.
  3. Type the name or IP address of the host in the Host Name/Address field.
  4. If the host requires a user name, type it in the Username field.
  5. dataComet tries to select an appropriate terminal type using its default Automatic setting. The host may require you to identify another terminal type. If so, select one from the list provided.
  6. Click "OK" to establish the connection.
  7. When the host's menu appears, follow the on-screen directions to navigate through the system.

Saving a Telnet configuration

You can save Telnet configurations for hosts that you want to connect to regularly. This allows you to begin a Telnet session quickly -- just double-click the saved dataComet icon -- without having to specify the host name, window name, and session characteristics each time you connect to the host.

To save a Telnet configuration:

  1. Follow steps 1 to 6 in "Establishing a Connection."
  2. Choose how you want to display characteristics for the session. Select the "Control" menu, and specify the following session characteristics:
    • Screen Size (usually 24 rows x 80 columns, on the "Emulator" menu)
    • Key Mapping (on the "Emulator" menu)
    • Font
    • Size (of font)
    • Color
  3. Select "Save configuration" from the File menu. A directory dialog box appears with the prompt to name the session.
  4. Type a name for the session in the Save configuration in field, and click "Save" to save the current settings. Save the Telnet session to your desktop or a folder of your choice.
  5. To access a saved configuration, double-click your dataComet icon.

Running multiple connections

You can establish multiple connections to a single host or to several different hosts concurrently. When you have more than one Telnet connection, it's a good idea to name each session. dataComet will display each session name in the title bar. To switch between active sessions, click the session window or select the session name from the Window menu. Remember to log off each host before quitting dataComet.

Closing a connection to a remote host

Each host should tell you how to log off the service when you have completed your work. The log-off directions usually appear on the menu when you first log on. At the host's prompt, type the command to quit the system.

If no log-off command was provided, type logout at the host's prompt or select "Close" from the File menu. If you have not previously saved a configuration for this host, a message asking "Save new document for ___?" appears. If you wish to save a configuration, click "Save" and follow the directions in "Saving a Telnet Configuration" above.

Quitting dataComet

After you have finished using a remote host, make sure you log off the host, then quit dataComet.

To quit dataComet, select "Quit" from the File menu.

Example: Establishing a Telnet session to use public Lynx services

  2.     Select "New" from the File menu.
  3.     Type lynx.cc.ukans.edu in the Host Name/Address field.
  4.     Click "OK" to establish the connection.
  5.     At the login screen, follow the directions on the screen to connect to the desired service.
  6.     To quit, type q at the prompt, then press "y".
