Starting HDSterm
This page describes techniques to start HDSterm, including rlogin commands.
HDSterm Window
The HDSterm window with the Telnet selection menu is shown below.
HDSterm is loaded automatically if you start the ViewStation with server code Vnn-D.hds. HDSterm is used for Telnet Windows, Serial Windows, and Console Windows on the ViewStation.
Using the tty Telnet Client
If you have selected a server code version that doesn't load HDSterm, your Telnet selection will use the ViewStation's tty client with a limited ANSI emulation. The tty Telnet client is loaded automatically if you start the ViewStation with server code Vnn.hds. This client is commonly used with ViewStations with 4 MB of memory.

The "Ok" button selects your settings and closes the dialog box; the "Apply" button applies your settings immediately so you can see their effect; and the "Cancel" button closes the dialog box.
The "Window" Dialog Box
This dialog box selects features about the HDSterm window itself, such as window size and font. The selections are:
Vertical scroll bar This selection creates or removes a vertical scroll bar in the HDSTerm window. You can use the scroll bar to move up and down in the window. Utilizing DEC VT320 commands, you can also use the cursor keys for line by line movement or the Shift-cursor keys for screen by screen movement.

Some application programs want the special sequences for correct operation. This can also be set with a DEC escape sequence.
