PASSPORT VT/220 Telnet Client

VT/220 and VT/100 Terminal Emulator

PASSPORT VT/220 Telnet Client Free Trial Download

The PASSPORT VT/220 telnet client provides high quality, reliable VT/220 UNIX® host access. In addition, PASSPORT is fully compatible with Windows Vista®.

The PASSPORT VT/220 terminal emulator is extremely cost effective. Zephyr provides a subscription based licensing program that reduces your terminal emulation software acquisition cost and maintenance cost significantly. This makes upgrading from an older version of Attachmate EXTRA!®, IBM Personal Communications Program®, NetManage Rumba® or WRQ Reflection a very attractive proposition.

VT/220 Telnet Client Deployment

There are actually two PASSPORT products. Each product uses a different method of deployment.

PASSPORT PC TO HOST® is a desktop-based VT/220 telnet client. This product is similar to other desktop Windows programs. PASSPORT is installed with a Windows setup program. It can also be deployed using SMS, MSI or deployed from a Citrix terminal server. PASSPORT PC TO HOST® also includes VT420, VT100, SCO ANSI, Wyse 60, TN3270 and TN5250 terminal emulators.

PASSPORT WEB TO HOST® is a web based VT/220 telnet client deployed from a web server. The VT/220 terminal emulator is installed on a web server and provides an administrator program for centralized configuration and administration. All software and configuration files reside on the web server. When the terminal emulator is run, an ActiveX applet is downloaded from the web server to the client desktop and run inside of Internet Explorer. The ActiveX component is only downloaded the first time a session is launched, or whenever the server version of the ActiveX component changes to a newer version. The ActiveX client running inside Internet Explorer makes a direct VT52, VT/100 or VT/220 connection to the DEC or UNIX® host system.

VT/220 Connection Support

PASSPORT supports the telnet host access features defined in the IETF Telnet specifications, DEC VT52, DEC VT100, VT220 and VT420 Programmer's Reference manuals. Telnet terminal emulation uses the TCP/IP Internet protocol for communication between a telnet client and a telnet server. PASSPORT is compatible with all DEC and UNIX® hosts that adhere to these specifications. Both 7-bit and 8-bit VT emulation are supported.

PASSPORT provides a method to specify the text string used for the Telnet device type. PASSPORT uses the standard telnet device types "VT52", "VT100", "VT220" and "VT420". However, some VT hosts may require a non-standard telnet device type such as "DEC-VT220". Auto-reconnect is a configurable option that can automatically re-establish the emulator session after a telnet logoff is performed. Hot back up for connection to alternate IP host names is also provided.

FTP File Transfer with the PASSPORT VT/220 Telnet Client

FTP (File Transfer Protocol) is used when transferring files between a PC and an DEC or UNIX® host system. This protocol does not use the VT/220 terminal emulator session. An FTP server must be present on the host system. The FTP file transfer is actually a separate PC program and can be launched from the terminal emulator menu command or from the Windows Start->Programs menu. Transferring of files can be initiated in multiple ways, including drag and drop and cut/copy/paste. The FTP client has the look and feel of Windows Explorer with a menu bar, toolbar, status bar, three window panes (PC directory structure and file list, host directory structure and file list, connection log and error messages) that can be interactively resized and displayed as icons, details or list. The PASSPORT FTP client program adheres to full compliance with the IETF RFC 959 (File Transfer Protocol) specifications. FTP is a standard Internet protocol, just like the telnet protocol is.

Macro Scripting

The PASSPORT macro scripting language is based on the Microsoft Visual Basic scripting language. Macro scripts are used to automate common repetitive tasks. A macro script can be assigned to a key on the keyboard, keypad, toolbar, button bar or mouse button. A macro script can be run when hotspot text is clicked on with the mouse. A start-up logon macro can be configured to automatically run after connection when the host session is established.

When a macro command is executed, PASSPORT runs a separate program that is actually a HLLAPI application. This HLLAPI application utilizes both the Microsoft VB Script and the PASSPORT HLLAPI module to run the macro.

Quicktrial or Download Options

There are two ways to evaluate the PASSPORT VT/220 Telnet Client: either download a copy of the software or do a QuickTrial of the PASSPORT WEB TO HOST® application. With QuickTrial, there is no server installation, you simply download the client from our web server. This is a fast and easy way to look at the PASSPORT WEB TO HOST® software. For those that want to install the PASSPORT WEB TO HOST® software on their own web server, you can download the full working copy of the software and complete a full evaluation.
