Simply head to the Desk menu and select New Window. A new MDI window should open named <Untitled>. Here we can right-click within the window and select Presentation and change the title to "VT320" and the icon to whatever we desire. Boom, we have a group to keep all our terminal sessions nice and neat.

Inside our VT320 group, we can right-click and select New Item and then VT320 Application…

This will then present a dialog that asks for Host and Command:

We can select which host we wish to use by either typing its name or selecting one from the drop-down list.

For just a terminal connection, leave Command empty.

Let's change the icon to something… nicer. We can do that by right-clicking on our new VT320 Application icon and selecting Presentation. Feel free to rename it to something better–though bear in mind that the hostname prefix will always be present. I simply rename mine to the type of terminal emulation I use, e.g. "VT220", "VT320" etc.

You can press Browse… and select an icon source (such as vwhosts.dll).

Once you've made it as pretty as you want, we can now configure the actual terminal emulation.

Right-click on it and select Terminal…. We can set various emulation options here.

To change the emulation type, we can use Identity to change between VT100, VT220, VT320 et al. For older hosts, I use VT220 with compatibility set to VT100.

You can also use the Key Map File option to change key maps if you want.

If you wish to change font settings, you can right-click on the item and select Window… to change various settings there. Using Fixed with a specific font size is probably advisable.

Now we're ready to connect.
