An ActiveX control for viewdata emulation that faithfully displays full 40-column viewdata
terminal screens from within an IE browser. It is IP-based and features powerful scripting
facilities for quick and easy connections to different services. Allows for secure connections
with SSL server authentication and encryption.
An accurate and straightforward IP-based viewdata emulator.
The browser will download the control when an HTML page first requests it and then communicates
with the control via the controls Properties (parameters) and Methods (functions or procedures).
The calling HTML page will contain the settings for the viewdata service for GoVX to connect to
and these are simply the host domain name, the host port number and the 'search/send' string or
script (if required). If a secure (SSL) connection is called for then the host is authenticated
via its server certificate and encryption is employed. The search/send string can be used for
automatic login to a service and consists of one or more pairs of question/response substrings
separated by the ‘/’ character. For example:
A powerful scripting facility is also available for more demanding tasks.
During emulation the keyboard is mapped as you would expect.
In addition, the auxiliary keypad ‘-‘ key maps to ‘Reveal Display’.
Displayed screens can be printed or saved to disk as viewdata (.vdt) files.
If you have Internet Explorer you can try a
of GoVX (use any text for ABTA number and password as these are not verified).
You can also try it with an
automatic login script.
