+Skeleton driver for VT220-compatible terminals by C. Itoh/CIE Terminals.
+
+The CIT-220+ Video Terminal was introduced as a direct competitor to DEC's VT220. It copied the design of the VT220 closely
+enough to provoke a lawsuit, which led to its eventual withdrawal in favor of its successor, the CIT224.
