The VTTEST VT100/102 Terminal Emulation Test

The VTTEST program was written in 1983-85 by Per Lindberg of Stockholm University in Sweden to exercise and test all the features of a Digital Equipment Corporation (DEC) VT100 or VT102 terminal or software that emulates one of these terminals. Incidentally, the primary additional feature of the VT102 terminal over the VT100 is character insertion and deletion, important in text-editing applications (like vi or EMACS), especially on slow connections.

You may obtain the C-language source code for the VTTEST program by ftp, compile it on your UNIX system (or adapt it to others), and run the tests yourself:

The VTTEST program does not test any features of the VT220 or above, nor of esoteric VT models like VT125, VT131, etc. (Update: newer versions of VTTEST have been created since this page was written).

The following sheet may be used to administer the test. There are 100 points, plus 10 possible extra-credit points, so the highest possible score would be 110. To minimize confusion and promote fairness, begin with your emulator set to:


VTTEST VT100/VT102 Compatibility Test Score Sheet Program and version: _____________________________________ Date: _________ Score: ____________ + Extra credit: ___________ = Final score: ___________ Check box if test passed.
