Connecting to the Host System - VT

VT Define New Connection

Prior to establishing a host system connection, BlueZone VT users must set Session Configuration parameters. Session configuration consists of:

Selecting an existing or Defining a new Connection Type and configuring its connection settings.

This section deals with Defining a New Connection. The BlueZone VT Define New Connection property sheet consists of a Connection, Firewall and Security tabs.

Connection Tab

Telnet Connection ----

Connection Name: A unique name used to identify this collection of Connection settings.
Host Name/Address: Specifies the computer name (in Internet format) or the IP address (in dotted decimal format) of the VT server. An IP address is the preferred format, eliminating the requirement for domain name resolution, resulting in a faster connection time and recovery if the name cannot be resolved.
TCP Port: Specifies the TCP port number to which to connect. The default is 23.
Backup Host: Specifies the backup host to which BlueZone will connect if the primary host is not available. Backup hosts are selected from the Connection List.
Terminal: Choose the Terminal Type that you want to emulate from the List box.
Terminal ID: This will automatically change with the chosen Terminal setting above however, you can override this value with the setting of your choice.

Default Screen Size ----

Rows: The number of displayable rows used by the host.
Columns: The number of displayable columns used by the host.

Options ----

Answerback: Place the desired Answerback in this box, if any.
Local Echo: When checked, BlueZone VT will display the characters (locally) pressed by the user for hosts that do not echo back the characters that are sent to it. If you are seeing double characters, then un-check this checkbox.
Force Auto Wrap: checking this box will force BlueZone VT to word wrap any characters that would normally extend off the right hand side of the screen. This will override the setting that is sent down from the host.
Disable Dimming Colors: Checking this box will turn off BlueZone VT's Character Dimming feature. This can be helpful when it is difficult to distinguish dim characters on the screen.

SEE VT Session Colors for more information on selecting color options for Bold and Dim intensities.
