+# 2020/12/26:
+# Tested terminology 1.8.1 using tack and vttest.
+# tack -
+# flash does not work
+# italics and crossed-out text work
+# no meta mode
+# vttest -
+# DA1 says this is a VT420 with with 132 columns, NRCS, horizontal scrolling
+# DA2 says this is a VT510, version 33.7
+# NRCS does not work, program hangs in the locking shift test.
+# some of the VT420 rectangle operations work
+# left/right margins do not work
+# most of DECSCUSR works
+# most problems with bce are fixed.
