Vttest is a program designed to test the functionality of a VT100 terminal (or emulator thereof). It tests both display (escape sequence handling) and keyboard.

The program is menu-driven and contains full on-line operating instructions.

• To run a given menu-item, you must enter its number.

• Menu items start at zero; this is the “Exit” item in almost all cases.

• You can run all menu-items (for a given level) by entering an asterisk, i.e, “*'.

• You can force a repaint of the menu items by entering “?”.

• A few menus can be more than one page. Use “n” and “p” to switch to the next or previous page.
