VT-10-Squared emulates a limited, but basic, set of VT-100
         functions. It provides a full 80-column screen by use of a
         software handler which uses a 3-pixel-wide character set.
         While the characters are not perfect, you will find them
         quite readable on a crisp monitor or black-and-white TV.
         VT-10-Squared does not support all VT-100 capability,
         particularly special graphics characters, special character
         sizes, and 132-column screen. As a result, it will not work
         properly with some DEC products.
