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. You
can run all menu-items (for a given level) by entering an asterisk, i.e,
|vttest||test VT100-type terminal|
